5 things that humans can not do, science says!

in #blog7 years ago

The human body is wonderful, no one doubts it. It is an incredible work of nature, capable of doing many fabulous activities. However much it hurts us in the ego, there are a couple of things that our body can not do, no matter how hard we try. You do not believe me? Science tells us what the five actions humans are unable to do.

1 Licking Your Elbow

Unless you're Slenderman, you will not be able to reach your elbow with your tongue. No matter how many times you try, you will not make it (surely you are doing it right now). Some young children can do this because the calcification in their bones is not over and they are more flexible. However, from the age of 5 we can not do it anymore.

2 Sneezing with your eyes open

Close your eyes during a sneeze is a reflex act. This is because there is a stimulus in our brain, which comes directly to our eyelids and causes them to close over our eyes. This is an act of protection of our body, which tries to prevent our eyes from catching an infection with our own sneeze.

3 Break an egg with two fingers

We can break it by striking it against something or by clenching its fist tightly around it. What we can not do is break it by placing the index finger and thumb on the top and bottom of the egg. This is because both ends are the strongest parts of the egg and withstand the pressure we exert on it.

4 Tickle Yourself

We are very sorry, but this fun and sometimes desperate activity you can not do it alone, you need a tickle partner. Everything is due to proprioception, which is the ability to detect our own body and to differentiate when a movement comes from it, in what position we are and if we touch any part of our organism. This perception removes the unexpected from tickling (and thus fun).

5 Move your ears

In fact, only 1% of the population can move them, specifically the upper part. This is because the movement of this part of the body was suppressed by evolution. Our ancestors could move them because it was a necessity to listen to their predators better, but this skill is no longer indispensable (just to surprise your friends).
