Trauma permanently changes us.

1. Trauma permanently changes us.
This is the big, scary truth about trauma: there is no such thing as “getting over it.” The five stages of grief model marks universal stages in learning to accept loss, but the reality is in fact much bigger: a major life disruption leaves a new normal in its wake. There is no “back to the old me.” You are different now, full stop.
This is not a wholly negative thing. Healing from trauma can also mean finding new strength and joy. The goal of healing is not a papering-over of changes in an effort to preserve or present things as normal. It is to acknowledge and wear your new life — warts, wisdom, and all — with courage.
2. Presence is always better than distance.
There is a curious illusion that in times of crisis people “need space.” I don’t know where this assumption originated, but in my experience it is almost always false. Trauma is a disfiguring, lonely time even when surrounded in love; to suffer through trauma alone is unbearable. Do not assume others are reaching out, showing up, or covering all the bases.
It is a much lighter burden to say, “Thanks for your love, but please go away,” than to say, “I was hurting and no one cared for me.” If someone says they need space, respect that. Otherwise, err on the side of presence.
3. Healing is seasonal, not linear.
It is true that healing happens with time. But in the recovery wilderness, emotional healing looks less like a line and more like a wobbly figure-8. It’s perfectly common to get stuck in one stage for months, only to jump to another end entirely … only to find yourself back in the same old mud again next year.
Recovery lasts a long, long time. Expect seasons.
4. Surviving trauma takes “firefighters” and “builders.” Very few people are both.
This is a tough one. In times of crisis, we want our family, partner, or dearest friends to be everything for us. But surviving trauma requires at least two types of people: the crisis team — those friends who can drop everything and jump into the fray by your side, and the reconstruction crew — those whose calm, steady care will help nudge you out the door into regaining your footing in the world. In my experience, it is extremely rare for any individual to be both a firefighter and a builder. This is one reason why trauma is a lonely experience. Even if you share suffering with others, no one else will be able to fully walk the road with you the whole way.
A hard lesson of trauma is learning to forgive and love your partner, best friend, or family even when they fail at one of these roles. Conversely, one of the deepest joys is finding both kinds of companions beside you on the journey.
5. Grieving is social, and so is healing.
For as private a pain as trauma is, for all the healing that time and self-work will bring, we are wired for contact. Just as relationships can hurt us most deeply, it is only through relationship that we can be most fully healed.
It’s not easy to know what this looks like — can I trust casual acquaintances with my hurt? If my family is the source of trauma, can they also be the source of healing? How long until this friend walks away? Does communal prayer help or trivialize?
Seeking out shelter in one another requires tremendous courage, but it is a matter of life or paralysis. One way to start is to practice giving shelter to others.
6. Do not offer platitudes or comparisons. Do not, do not, do not.
“I’m so sorry you lost your son, we lost our dog last year … ” “At least it’s not as bad as … ” “You’ll be stronger when this is over.” “God works in all things for good!”
When a loved one is suffering, we want to comfort them. We offer assurances like the ones above when we don’t know what else to say. But from the inside, these often sting as clueless, careless, or just plain false.
Trauma is terrible. What we need in the aftermath is a friend who can swallow her own discomfort and fear, sit beside us, and just let it be terrible for a while.
7. Allow those suffering to tell their own stories.
Of course, someone who has suffered trauma may say, “This made me stronger,” or “I’m lucky it’s only (x) and not (z).” That is their prerogative. There is an enormous gulf between having someone else thrust his unsolicited or misapplied silver linings onto you, and discovering hope for one’s self. The story may ultimately sound very much like “God works in all things for good,” but there will be a galaxy of disfigurement and longing and disorientation in that confession. Give the person struggling through trauma the dignity of discovering and owning for himself where, and if, hope endures.
8. Love shows up in unexpected ways.
This is a mystifying pattern after trauma, particularly for those in broad community: some near-strangers reach out, some close friends fumble to express care. It’s natural for us to weight expressions of love differently: a Hallmark card, while unsatisfying if received from a dear friend, can be deeply touching coming from an old acquaintance.
Ultimately every gesture of love, regardless of the sender, becomes a step along the way to healing. If there are beatitudes for trauma, I’d say the first is, “Blessed are those who give love to anyone in times of hurt, regardless of how recently they’ve talked or awkwardly reconnected or visited cross-country or ignored each other on the metro.” It may not look like what you’d request or expect, but there will be days when surprise love will be the sweetest.
9. Whatever doesn’t kill you …
In 2011, after a publically humiliating year, comedian Conan O’Brien gave students at Dartmouth College the following warning:
"Nietzsche famously said, ‘Whatever doesn’t kill you makes you stronger.’ … What he failed to stress is that it almost kills you.”
Odd things show up after a serious loss and creep into every corner of life: insatiable anxiety in places that used to bring you joy, detachment or frustration towards your closest companions, a deep distrust of love or presence or vulnerability.

There will be days when you feel like a quivering, cowardly shell of yourself, when despair yawns as a terrible chasm, when fear paralyzes any chance for pleasure. This is just a fight that has to be won, over and over and over again.
10. … Doesn’t kill you.
Living through trauma may teach you resilience. It may help sustain you and others in times of crisis down the road. It may prompt humility. It may make for deeper seasons of joy. It may even make you stronger.
It also may not.
In the end, the hope of life after trauma is simply that you have life after trauma. The days, in their weird and varied richness, go on. So will you.

Life Lessons From Harvard Business School 1963

LEADERSHIP
ANONYMOUS:
I would have been a better leader if I had been less cocky in my early career, and more confident in my middle career.
ROBERT K. BOWMAN:
A successful leader:
  • Knows as much as he can about his organization’s mission
  • Believes in the mission
  • Communicates the mission clearly
  • Points the way
  • Gets out of the way
CAREER
RON LESLIE:
Steps to find fulfilling work:
  1. Take the initiative to investigate the places you think are of interest. Ask good questions.
  2. Go with the self-assurance of having written on an index card each of your past accomplishments(including where you simply helped other people do their thing) in three forms:Use those cards deftly to encourage people to talk to you — showing you listen on their level and understand whatever they tell you. Remember: The more they talk, the smarter they’ll think you are.
    1. A simple phrase; e.g., “top salesman in New York office for three years”
    2. A three-sentence statement of the problem, your solution, and the result
    3. A one-page explanation or anecdote to share if asked to give details 
MARRIAGE & FAMILY
RALPH LINSALATA:
  • Tell your spouse and children that you love them every day, no matter how you feel.
  • Do not bring your problems home with you.
  • Realize the joy that comes from helping your spouse and children excel in their fields of interest and enjoy themselves.
  • Develop within your family a sense of obligation to help others.
  • Spending quality time with your family — not just time — is critical.
  • Choose a spouse who will understand and support you, and one for whom you will do the same. Life is much better if you can help each other grow and expand your knowledge, experiences, friends, and capabilities. 
RON LESLIE:
The sweetest words in the English language are, “Granddad, would you like to …?”
BUSINESS
DONALD P. NIELSEN:
  • Not all decisions turn out well. Be prepared to deal with problems over which you have no control.
  • Almost everything will require more money and more time than you think.
  • Never settle for “good enough.” Always strive for excellence.
  • Set high expectations for yourself and those with whom you work.
  • Move quickly to deal with people issues.
  • Hiring smart, driven people is a ticket to your own success.
WEALTH
WARREN BATTS:
I was born in 1932 and grew up during the Depression. In the beginning, poverty was the level to which I aspired. When I reached it, my next goal was to get out of debt. That took several years. Then my goal was to become financially independent. After reaching independence, more money was not a great motivator for me. My interest became trying to make a difference — making the company I worked for successful, and working for my church and other volunteer organizations.
GROWING OLDER
ANONYMOUS:
Retire to something — not from something. Stay engaged. Be physically active and intellectually curious.
 CHARITY & SPIRITUALITY
J. LAWRENCE WILSON:
If one is devoted solely to promoting the welfare of himself, his family, and his friends, life can be barren. Charity, faith, and spirituality enrich one’s life. Faith or the belief in a power greater than oneself seems to be important for humans, for spirituality is a part of every culture. If this spirituality fosters concern for the welfare of others, it is of great benefit to society. No matter what a person’s professed faith, I admire him if he is charitable.
HAPPINESS & SUCCESS
HENRY A. GILBERT:
Success and wealth are being a lover and being loved.
Success is using your tools and powers to enhance the lives and success of others.
Success is capitalizing on economic opportunities yet treating others with over-reaching kindness.
J. LAWRENCE WILSON:
When I think back over my career, I am struck that my fondest memories are of people rather than experiences, places, or accomplishments.
TURNING POINTS
RALPH LINSALATA:
What did I learn from the turning points in my life? Look for great colleagues, role models, and teachers. Be certain to understand the opportunities relative to the risks, and how the risks can be avoided. Recognize your strengths and weaknesses, and act accordingly. Play to your strengths while you work, but work on your weaknesses.
GERALD (JERRY) WOLIN:
Many things that happened in my career were the result of random acts. The important thing is to keep your eyes open to recognize the right moves.
LIFE’S LESSONS
JOSE M. FAUSTINO:
I switched fields twice in my academic career — I believed the entire experience was part of growing up. The lesson here for young people: Do not hesitate to switch interests, majors, or fields of concentration. Find your preference or your passion, then focus on it to your heart’s content.
Success is a journey – not a race. Prepare well, retain good practices, and make a habit of effective strategies:
  1. Do not be content to be average. Mediocrity breeds boredom, poor opportunity, and an unsatisfactory lifestyle. Instead, decide to excel in everything you do, and be distinctive, if not unique, in your approach.
  2. Take well-analyzed risks, particularly when there is everything to gain and little to lose. Do not be afraid of rejection when you have competently and ethically tried to succeed.
  3. Be skilled in political strategy. Interpersonal, leadership, and motivational skills are all important for success, but few consider political strategy. In my mind, there is organizational politics in any group with more than three people.
JOHN A. MOELLER:
An important lesson in life is learning whom you can rely on, depend on, and trust, and whom you cannot. Only experience and “gut feel” can teach this. Human nature and values — whether of business owners, top management, associates, or staff — vary all over the place. Steering your life, family, career, time, investments, and loyalty toward those you can trust and rely upon is a priority.
Never forget where you came from, and always remember what you are here for. Be true to your values and faith. We are here for a purpose. Enjoy the ride.

Everything You Need To Know About Wine and Pairing Wine With Food

There's a lot more to becoming a wine expert than tossing back a glass now and then.
You've got to know the vocab — tannin, bouquet, terroir, aroma — not to mention how to hold a glass, recognize flavors, and know when to drink it.
Luckily, London-based company Datadial developed a helpful infographic for their client WineInvestment that breaks down everything a budding wine enthusiast needs to know (first found at Visual.ly).
We broke apart the infographic into nine handy illustrations.
Let's start with the breakdown of the bottle. The name of the company that produces the wine will be at the top, followed by the variety of wine, the region and type of grapes used, and the year it was made. Alcohol content will be at the very bottom of the label:
wine bottle beginner's guide to wineCourtesy of Datadial
Different wines should be served at different temperatures. Red wine should be room temperature, or about 20-25 degrees C, whilepink or rosé wines should be served slightly chilled around 7-13 degrees C.
White wine and sparkling wine should both be cold — keep them in the fridge so that they're below 5°C, or 40°F.
temperature beginner's guide to wineCourtesy of Datadial
Different types of glasses are best for different types of wine. Of course, you don't need all the variety of glasses in your home, but when picking out glasses, choose ones that complement the type of wine you favor.
It's always a good idea to have champagne flutes and port glasses on hand, as well.

To hold and swill wine like an expert, hold the glass by the stem. This is important especially with chilled wines since the heat from your hand will warm the bowl and alter the taste of the wine.
Then rotate your wrist so the wine gently swirls around the bowl. This allows the smell of the wine to fill the bowl, which is important for the flavor profile.

Wine are not only red, pink, or white. In fact, the shade and hue of the wine indicates its age and the type of wine — whether it's light- or full-bodied, or the different kinds of rosé.
And if a wine looks cloudy, that usually means there's something wrong with it. Ask for a different glass, or throw out the wine.

The alcohol content in wine ranges from 11-14%. Lighter wines tend to have less alcohol, whereas bolder wines will have more.
Make sure to drink light wines 3 days after opening. Bolder wines can last up to 10 days.

To sound cool in front of all your oenophile friends, it's important to know the aroma of your wine. Fruity, sweet, spicy, herbal, mineral, and floral are some of the more common aromas.
Experts can even taste the underlying flavor notes of the wine. Here are some of the common ones:
aroma beginner's guide to wineCourtesy of Datadial
Ah, tannins: One of the more confusing components when experts talk about wine. All you really have to know is that a tannin is a textural element of the wine that makes it taste dry.
Here's what you don't have to know, but might find interesting: Tannin is a naturally occurring polyphenol found in plants, seeds, bark, wood, leaves, and fruit skins. Tannins add bitterness, astringency, and a complex flavor to your wine.
Typically, tannins in wine either come from the grapes' skin, seeds, or stems. Tannins can also be from the wood of the barrel that the wine was aged in.
Wine tannins are most commonly found in red wine, although some white wines have tannins from being aged in wooden barrels.
tannins beginner's guide to wineCourtesy of Datadial
Terroir is a vocab word that only true wine connoisseurs are familiar with — or those who have been to the NYC wine bar by the same name.
Essentially, it's the set of special characteristics (including climate, soil type, topography, and other plants growing in the area) that influence grapes where they're grown.
The terroir affects the flavor of the grapes, and is what makes all wines unique.

The Electromagnetic Spectrum

The Electromagnetic Spectrum, from Radiowaves with longest wavelength, largest size and shortest frequecy to Gamma-rays with shortest wavelength, smallest size and largest frequecy, is the range of all possible frequencies of electromagnetic radiation.

These electromagnetic radiation mainly come from the sun and stars and then penetrate into the earth's atmosphere but not all can penetrate as seen in the EM spectrum infographic provided. So since they do not penetrate into the earth's atmosphere then we can find and also produce them here on earth. Each radiation also has its own temperature range.

A Fact you need to know: The biggest gamma-ray generator of all is the Universe.
The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation. The other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, ultraviolet light, X-rays and gamma-rays.

You know more about the electromagnetic spectrum than you may think. The image below shows where you might encounter each portion of the EM spectrum in your day-to-day life.
The electromagnetic spectrum shown with familiar sources
The electromagnetic spectrum from lowest energy/longest wavelength (at the top) to highest energy/shortest wavelength (at the bottom). (Click image for a larger version.)
Radio: Your radio captures radio waves emitted by radio stations, bringing your favorite tunes. Radio waves are also emitted by stars and gases in space.Microwave: Microwave radiation will cook your popcorn in just a few minutes, but is also used byastronomers to learn about the structure of nearby galaxies.
Infrared: Night vision goggles pick up the infrared light emitted by our skin and objects with heat. In space, infrared light helps us map the dust between stars.
Visible: Our eyes detect visible light. Fireflies, light bulbs, and stars all emit visible light.
Ultraviolet: Ultraviolet radiation is emitted by the Sun and are the reason skin tans and burns. "Hot" objects in space emit UV radiation as well.
X-ray: A dentist uses X-rays to image your teeth, and airport security uses them to see through your bag. Hot gases in the Universe also emit X-rays.
Gamma ray: Doctors use gamma-ray imaging to see inside your body. The biggest gamma-ray generator of all is the Universe.

Is a radio wave the same as a gamma ray?

Are radio waves completely different physical objects than gamma-rays? They are produced in different processes and are detected in different ways, but they are not fundamentally different. Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation.
Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each traveling in a wave-like pattern at the speed of light. Each photon contains a certain amount of energy. The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.

Measuring electromagnetic radiation

Electromagnetic radiation can be expressed in terms of energy, wavelength, orfrequency. Frequency is measured in cycles per second, or Hertz. Wavelength is measured in meters. Energy is measured in electron volts. Each of these three quantities for describing EM radiation are related to each other in a precise mathematical way. But why have three ways of describing things, each with a different set of physical units?
Illustration showing comparison between wavelength, frequency and energy
Comparison of wavelength, frequency and energy for the electromagnetic spectrum. (Click image for a larger version.)
The short answer is that scientists don't like to use numbers any bigger or smaller than they have to. It is much easier to say or write "two kilometers" than "two thousand meters." Generally, scientists use whatever units are easiest for the type of EM radiation they work with.
Astronomers who study radio waves tend to use wavelengths or frequencies. Most of the radio part of the EM spectrum falls in the range from about 1 cm to 1 km, which is 30 gigahertz (GHz) to 300 kilohertz (kHz) in frequencies. The radio is a very broad part of the EM spectrum.
Infrared and optical astronomers generally use wavelength. Infrared astronomers use microns (millionths of a meter) for wavelengths, so their part of the EM spectrum falls in the range of 1 to 100 microns. Optical astronomers use both angstroms (0.00000001 cm, or 10-8 cm) and nanometers (0.0000001 cm, or 10-7 cm). Using nanometers, violet, blue, green, yellow, orange, and red light have wavelengths between 400 and 700 nanometers. (This range is just a tiny part of the entire EM spectrum, so the light our eyes can see is just a little fraction of all the EM radiation around us.)
The wavelengths of ultraviolet, X-ray, and gamma-ray regions of the EM spectrum are very small. Instead of using wavelengths, astronomers that study these portions of the EM spectrum usually refer to these photons by their energies, measured in electron volts (eV). Ultraviolet radiation falls in the range from a few electron volts to about 100 eV. X-ray photons have energies in the range 100 eV to 100,000 eV (or 100 keV). Gamma-rays then are all the photons with energies greater than 100 keV.

Why do we put telescopes in orbit?

Illustration showing how far into the atmosphere different parts of the EM spectrum reach
The Earth's atmosphere stops most types of electromagnetic radiation from space from reaching Earth's surface. This illustration shows how far into the atmosphere different parts of the EM spectrum can go before being absorbed. Only portions of radio and visible light reach the surface. (Credit: STScI/JHU/NASA)
Most electromagnetic radiation from space is unable to reach the surface of the Earth. Radio frequencies, visible light and some ultraviolet light makes it to sea level. Astronomers can observe some infrared wavelengths by putting telescopes on mountain tops. Balloon experiments can reach 35 km above the surface and can operate for months. Rocket flights can take instruments all the way above the Earth's atmosphere, but only for a few minutes before they fall back to Earth.
For long-term observations, however, it is best to have your detector on an orbiting satellite and get above it all!

Wanatirta in Indonesia



Wanatirta in central Jawa comes from Javanese which is a combination of words meaning Wana Forest and Tirta meaning Water. So Wanatirta implies Water Forest.

Geographically Wanatirta Village District of Paguyangan Brebes has no water shortages because there are many sources of water in the surrounding. Even if in other regions experiencing a long drought (no rain at all), in the surrounding of this temple will be blessed with water.

"ARCA TEMPLE". The temple is located in the west foot of Mount Slamet exactly in the middle of a coffee plantation that is protected from large trees are hundreds of years old.

Ten Comparisons Between Humans and Chimpanzees

"Give orange me give eat orange me eat orange give me eat orange give me you."
 
That's the longest string of words that Nim Chimpsky, a chimpanzee who scientists raised as a human and taught sign language in the 1970s, ever signed. He was the subject of Project Nim, an experiment conducted by cognitive scientists at Columbia University to investigate whether chimps can learn language.
After years of exposing Nim to all things human, the researchers concluded that although he did learn to express demands — the desire for an orange, for instance — and knew 125 words, he couldn't fully grasp language, at least as they defined it. Language requires not just vocabulary but also syntax, they argued. "Give orange me," for example, means something different than "give me orange." From a very young age, humans understand that; we have an innate ability to create new meanings by combining and ordering words in diverse ways. Nim had no such capacity, which is presumably true for all chimps.
Chimpanzees are our closest living relatives, and yet they were unknown to most of the world until Charles Darwin wrote about and popularized them in 1859. Much about them has only been discovered recently, and misconceptions abound due to the exaggerations and artistic license used in works of fiction. Nevertheless, our similarities and differences are not what many people think. By learning about our relatives we can better understand ourselves.

Number of Species
Orangutan Bw-E1280771919943
Chimpanzees are often incorrectly called monkeys, but they are actually in the great ape family just like us. The other great apes are orangutans and gorillas. There is only one species of human alive at present: homo sapiens. In the past, many scientists tried to argue that there were several species of human, and would often hasten to add that they themselves belonged to the ‘superior’ species. However, all humans can produce fertile children and so we are all the same species. Chimpanzees, on the other hand, are actually two species: pan troglodytes, the common chimpanzee, and pan paniscus, the gracile chimpanzee or bonobo. These two types of chimpanzee are completely separate species. Humans and both chimpanzee species evolved from a common ancestor, possibly sahelanthropus tchadensis, between five and seven million years ago. Only fossils of this ancestor remain.

DNA
200990121
It is often said that humans and chimpanzees share 99% the same DNA. Genetic comparison is not simple due to the nature of gene repeats and mutations, but a better estimate is somewhere from 85% to 95%. This figure may still sound impressive, but most DNA is used for basic cellular functions which all living things share. For example, we have about half the same DNA as a banana, and yet people do not use this to emphasize how similar bananas are to us! So 95% does not say as much as it first appears to. Chimpanzees have 48 chromosomes, two more than humans. It is thought that this is because in a human ancestor, two pairs of chromosomes fused into a single pair. Interestingly, humans have some of the least genetic variation of all animals, which is why inbreeding can cause genetic problems. Even two completely unrelated humans are usually genetically more similar than two sibling chimpanzees.

Brain Size
Chimp-Human Brain
The brain of a chimpanzee has a volume of 370mL on average. In contrast, humans have a brain size of 1350mL on average. Brain size alone, however, is not an absolute indicator of intelligence. There have been Nobel Prize winners with brains ranging from below 900mL all the way up to over 2000mL. The structure and organization of the various parts of the brain is a better way of determining intelligence. Human brains have a high surface area because they are much more wrinkled than chimpanzee brains, with greater numbers of connections between many of its parts. These, as well as a relatively larger frontal lobe, allow us much more of the luxury of abstract and logical thought.

Sociability

Chimpanzees spend a great deal of time socializing. Much of their socializing is grooming each other. Juvenile and adolescent chimpanzees will often play with, chase, and tickle each other, as will adults with their offspring. Shows of affection include hugging and kissing, which are done between chimpanzees of any age or gender. Bonobos are especially frisky, and nearly every show of affection is done sexually, regardless of gender. Chimpanzees strengthen friendships by spending extensive time grooming each other. Humans spend a comparable time socializing, albeit more through talking than grooming. Nevertheless, much of the vast amounts of inconsequential chatter we produce is simply a more sophisticated version of chimpanzee grooming – it serves little other purpose than to strengthen our relationship bonds. Humans also demonstrate stronger relationships through physical contact – a pat on the back, a hug, or a friendly shove. Primate social group sizes closely reflect their brain sizes. Chimpanzees have about 50 close friends and acquaintances, whereas humans have between 150 and 200.

Language and Facial Expressions

Chimpanzees have complex greetings and communications which depend on the social statuses of the communicating chimps. They communicate verbally using a variety of hoots, grunts, screams, pants, and other vocalizations. Most of their communication, however, is done through gestures and facial expressions. Many of their facial expressions – surprise, grinning, pleading, comforting – are the same as those of humans. However, humans smile by bearing their teeth, which is for chimps and many other animals a sign of aggression or danger. A much greater portion of human communication is done through vocalizations. Humans uniquely have complex vocal chords, allowing us a great range of sounds, but preventing us from drinking and breathing simultaneously like chimpanzees can. Moreover, we have very muscular tongues and lips, allowing us accurate manipulations of our voices. This is why we have pointy chins whereas chimps have receding chins – we attach our many lip muscles to the prominent lower chin, but chimpanzees lack many of these muscles and so do not need a protruding chin.

Diet
How-To-Make-A-Banana-Split
Chimpanzees and humans are both omnivorous (eat plants and meat). Humans are more carnivorous than chimpanzees, and have intestines more refined towards the digestion of meat. Chimpanzees will occasionally hunt and kill other mammals, often monkeys, but otherwise restrict themselves to fruit and sometimes insects. Humans are much more dependent on meat – humans can only obtain vitamin B12 naturally through eating animal products. Based on our digestive system and the lifestyles of extant tribes, it is thought that humans have evolved to eat meat at least once every few days. Humans also tend to eat in meals rather than continuously eating throughout the day, another carnivorous trait. This may be due to meats only being available after a successful hunt, and so are eaten in large quantities but infrequently. Chimpanzees will graze on fruits constantly whereas most humans will eat no more than three times in a day.

Sex
Chimpanzee Picture
Bonobos are renown for their sexual appetite. Common chimpanzees can become angry or violent, but bonobos defuse any such situation through sexual pleasure. They also greet and show affection to each other through sexual stimulation. Common chimpanzees do not engage in recreational sex, and mating only takes ten or fifteen seconds, often whilst eating or doing something else. Friendships and emotional attachments have no bearing on with whom a common chimpanzee mates, and a female in heat will generally mate with several males, who sometimes patiently wait their turn directly after each other. Humans experience sexual pleasure, like bonobos, however even sex for reproduction only takes much longer and requires more effort; long-term partnerships naturally form as a result. Unlike humans, chimpanzees have no concept of sexual jealousy or competition, as they do not take long-term partners.

Walking Upright

Both humans and chimpanzees are able to walk bipedally (on two legs). Chimpanzees will often do this to see further ahead, but prefer to move on all fours. Humans walk upright since infancy and have evolved bowl-shaped pelvises to support their internal organs while doing so. Chimpanzees, leaning forward during movement, do not need to support their organs with their pelvis and so have broader hips. This makes childbirth much easier for chimpanzees than for humans, whose bowl-shaped pelvis is in opposition to a large birth canal. Human feet are straight with toes at the front to help push directly ahead when walking, whereas chimpanzee feet have opposable big toes and are more like strong hands than feet. They are used for climbing and crawling, involving sideways, diagonal, or rotating movements.

Eyes

Humans have white around their irises, whereas chimpanzees usually have a dark brown color. This makes it easier to see where other humans are looking, and there are several theories as to why this is so. It may be an adaption to more complex social situations, where it is an advantage to see whom others are looking at and thinking about. It may help when hunting silently in packs, where eye direction is vital to communication. Or it may simply be a genetic mutation with no purpose – white around the iris is seen in some chimpanzees also. Both humans and chimpanzees can see in color, helping them to choose ripe fruits and plants to eat, and have binocular vision; their eyes point forward in the same direction. This helps see in depth and is crucial to hunting, rather than eyes on the side of the head like rabbits which help avoid being hunted.

Tool Use
Chimp Anvil
For many years, humans were considered to be the only tool-using animal. Observation in 1960 of chimpanzees using sharpened twigs to fish for termites has since changed this. Both humans and chimpanzees are able to modify their environment to forge tools to help with daily challenges. Chimpanzees will make spears, use stones as hammers and anvils, and mash leaves into a pulp to use as makeshift sponges. It is thought that as a result of walking upright, our front limbs were much freer to use tools, and we have refined tool use to an art. We live constantly surrounded by the products of this ability, and much of what people consider makes us ‘successful’ is rooted in our tool making.
