17 Fun Insights about The Human Body

Q. What happens with poop inside your body when you die?

All of your muscles relax after you die because they are no longer receiving instructions from your brain. As soon as your body expires, it releases urine and feces because the muscles holding those fluids back are no longer tense. You probably stink a little, and it’s a mess to clean up.

Q. What can I do to increase my height?

You could become an astronaut and live on the international space station. That’s good for as much as a 3% increase in your height. Problem is, you lose it when you come back to earth.

Also, there is a scientifically proven way to grow taller; It is called the “Ilizarov technique”. 

Briefly, the femur and/or the tibia and fibula are cut through. An external frame is attached to the ends of the cut bone through pins that go through the skin and into the bone.

Q. What is the largest and smallest bones in the body?

The largest bone in the human body is the femur, also known as the thigh bone. While the smallest bone is the stirrup bone, which is located inside your eardrum.

Origin of Goosebumps

Goosebumps evolved to make our ancestors’ hair stand up, making them appear more threatening to predators.


Q. Why do human beings yawn?

Scientists aren’t exactly sure why we yawn. Some say that when we are bored or tired, we just don’t breathe as deeply as we usually do, making our bodies take in less oxygen. Therefore, yawning helps us bring more oxygen into the blood and move more carbon dioxide out of the blood.

Q. Is it true that after 30, bones don’t get any stronger no matter what you eat?

In general, yes, bones grow in your teens and early twenties, and after that, your bones stop being metabolically active and you just work on not losing bone; but there is one major exception.


When you are breastfeeding, your bones become metabolically active again, as the milk for your baby is taken from your bones. And the calcium in your diet goes right into your bones to replace it.

This is nature’s way of making sure that the baby gets good milk, even if the mother is starving. But it means that a breastfeeding mother has a window in which she can increase bone density that she would not otherwise have.

Women who breastfed tend to have stronger bones and a lower risk of hip fractures than women who don’t.

Dermographism: the rarest body condition you will ever seen

Despite being quite rare, it is a benign and common skin condition. People with this condition develop hives or a localized hive-like reaction when they scratch their skin.

It can also occur when the skin is exposed to pressure or rubbing. This condition is also called cutaneous writing. It is one of the rarest conditions I have ever seen.

Q. Is muscle building an evolution failure?

If building up bigger muscles is good for us, why did we evolve to look like this and not with stronger muscles as apes do?

Scientists suspect that prehistoric peoples needed greater strength to make a living than we do.

Scientists who study human evolution think that modern people are less muscular than several related species that lived in the past. This reconstruction compares a muscular Neanderthal and a slim modern human. Scientists use the terms robust and gracile to describe the difference.

You can see that easily by comparing these two skeletons, Neanderthal on the left and modern human on the right.

Neanderthal bodies were powerfully built. This is reflected in the thick cortical bone in their pectoral and pelvic limb bones and their enlarged joint surfaces.

These characteristics indicate an adaptation to the generation of, and resistance to, high levels of muscular force. The thickening of long bone shafts would provide high resistance to bending forces acting on the bone and this is also reflected in the anterior-posterior bowing of Neanderthal femora (Ruff et al., 1993; Trinkaus et al., 1999).

Hand anatomy also indicates powerful musculature, as does the bowing of the radial shaft and the position of certain muscle attachments in the forearm (Trinkaus and Churchill, 1988; Niewoehner, 2006). All this suggests a high level of strenuous musculoskeletal activity for Neanderthals.

But modern people are probably taller than our prehistoric relatives.

There’s a lot of uncertainty about that because we don’t have many complete skeletons and modern humans vary a lot in height. That’s true for fossils as well. Homo erectus, for example, range from 185 cm (or 6 feet 1 inch for you Americans) down to 152 cm (just under 5 feet). That would make them below average in some wealthy countries but near average in poorer countries or in the 19th Century.

If God decides to redesign the human body and wants my input, This is what i will suggest

  1. No periods. We’d be better off without the monthly Niagara Falls.
  2. Sex is just a feel-good time. Fertilization is a different deliberate process for when you absolutely want kids. So, God should separate the two
  3. Improved Taste buds that like healthy green leafy veggies and food.
  4. Ability to fall asleep regardless of emotional state.
  5. Monkey tails with fingers for grabbing extra stuff and to scratch hard to reach places on the back
  6. Night vision.
  7. Replace nose hairs with gills to breathe underwater.
  8. Slowed Aging (Look 30 when you are 75).
  9. Men can breastfeed too.
  10. Wings. Nope, Redbull didn’t help.

Q. How could a medical examiner tell the cause of death?

Politely explained as best I can they slice the body from the neck to the crotch and take out the organs and weigh them and examine them as respectfully as they can.

They look for abnormalities in the skin car bath tissue abba body organs. For example, there was a person they pulled out of the river and when they cut you open they do like a Y on your chest so they can open it up like filleting the fish.

They sow it back together with something akin to burlap rope to hold you back together with no need for surgical incisions or cosmetic surgery as you’re going into the ground.

Then a check to see if your lungs had water in them. If you are in the water and you don’t have water in your lungs you died from some other problem other than drowning.

It’s like Colombo taking your body apart looking for evidence. Without a cigar.

The body cavities are searched to look for clues as to why the person died and they take blood tests and many other tests to find out why. sometimes results are inconclusive which means there are no answers and in other cases what the coroner has found can lead to charges.

Q. Does a woman’s body permanently change after childbirth? If so, what are these permanent changes?

Your pelvis widens. So that part of your body never goes back to pre-pregnancy size, because your bones have physically moved.

Stretchmarks don’t disappear. But do tend to fade.

A doctor will always be able to tell that she has given birth because her vagina has changed. Just the same as he can tell if a woman hasn’t had a vaginal birth.

Her brain will never be the same. Pregnancy and responsibility changes almost all women. So the focus is on the child, not on herself. This generally relaxes a little as the child gets older.

Once you have a child, life itself is never the same. Doesn’t matter whether you have a vaginal birth, a c section, or if you adopt.

Q. Who are the most famous celebrity couple with the greatest height difference?

Shaquille “Shaq” O’Neal and his former girlfriend Nicole Alexander

How about this couple?

Yes sir, Shaquille “Shaq” O’Neal and his former girlfriend Nicole Alexander.

Standing at seven foot one (2m16) and weighing 325 pounds (147 kg) in his prime, I just hope for Nicole that Shaq was not a restless sleeper.

And I can imagine other issues which could have become edgy when not handled with enough caution.

Q. Do your body know when death is near?

Back in 2015 I had gone to the store to do errands and was returning back to my assisted living facility. As I got close, something happened to my heart but I did not know what – I only knew I was desperate for help.

I pulled up and called inside for help. Not a single soul showed up even though I begged and begged. I was in a terrible state and finally was able to put the car in the parking space and dragged myself into the building into my room.

I recall looking at the date and time and nothing after that. The next day I awoke – my bed was wet ad it was about 24 hours since I collapsed. I have no memory of this but I must have called 911 and then passed out again. I awoke in the ambulance to hear the siren going and it speeding fast.

When I arrived at the loading dock in the hospital, the doctors were waiting and said to sign an o.k. for emergency heart surgery. I was dying. They did the surgery and saved my life with a difficult time-consuming recovery. I was told I was 95% dead and an angel above was looking over me.

Did I know I was dying?

No. But I knew I was critical from the siren and the voices on the telephone – “urgent, critical, near death”. I was very, very tired – like going into a deep sleep and if they had not done what they did, I would not have woken up.

I just felt like I was going into a fast, deep sleep – no pain. One other time years before I had major surgery and I do recall so vividly being in a long tunnel and I could be wrong but I sensed the color green (not white as is often the case). There were bright lights at the end. Then I was out and recall nothing but spent a long time in the hospital to recuperate. So more than that I do not know what to tell you.

I just pray and pray I go in my sleep as I don’t have any family and no one I was close to is left – or they are hours away. I don’t fear death but I fear the process of stepping over.

Is there any part in human beings that is not in other animals?

Not a physical part of the body but rather a construct of the mind … ‘Our EGO”.

Q. How does the body show you that it is dehydrated?

The easiest and normally most obvious way is to check the color of your urine. If you don’t feel the need to urinate, just drink a pint of water and wait a short while.

The chart below is a good chart to use if you have concerns – I think most of us know when it looks alright!

check the color of your urine from your body

This is the only organ that is useless in the human body!

The foreskin of the penis. No wonder modern societies have frequently remove it for thousands of years.

Q. What guides viruses within the body and tells them to move left or right until they locate their target?

Nothing. Viruses can’t move. They are not guided by anything. They float free until they hit a protein they can bond to. They are otherwise quite immotile and unguided. They have no sensory organs and no means to propel themselves.

You can think of viruses as being more like poisons than like living things. Poisons don’t obey commands or move left or right. They do what they do because of chemical reactions. It’s just that, unlike poisons, viruses inside a cell replicate.

In fact, the word “virus” comes from the Latin word for “poison.”
