These everyday activities are something that are never done out of purpose; we don't even think of doing it, and we just do it. Even while we do it, we never give a thought about what makes this actions occur. So, here is a list of things we regularly do but yet we don't know why we do it.
This explanation may seem a little absurd but this is real. Kissing is mere exchange of spits from one mouth to another but it holds other significance too.

After every ten seconds we step into darkness and we don't even find that weird because this is something natural. Blinking helps us clean the dust particles from our eyes and it spreads some lubricating fluids across the eyeball.
Often while having the dinner or talking to someone, we venture into our own thoughts. This zone out session is actually beyond our control because mind wanders randomly from one thought to another, while this is extremely good for creativity and imagination.

We hear a joke or we see some comedy movie and we burst out into a loud laughter. It is one of the most positive emotional expression which helps in relieving stress. However our ancestors mentioned that laughter is often a result out of panting.
We all cry whenever that heart pinches us pain. We are accustomed to those tears whenever we are sad and we are the only animals to sheds those salt water from our eyes.

Lets confront the reality, not everyone dies everyday but everyday there is someone who dies. Dying is the result of cells losing out its capacity to reproduce. Eventually our body is capable of only living 70 years or so.
Let's admit that we all fart and we should not be embarrass about it. Farting happens whenever we eat or drink. There are these microbes which comes and attacks the food we have, they break it down and release the by product which is a stinky gas. Well this stinky gas is hydrogen sulphide gas which we release and call it a fart.
Blushing is when the veins in the face dilate making our cheeks go red. This explanation is not as interesting as blushing. We usually blush when we meet someone important or we receive a compliment and its like that one activity which comes with a 'feel good' factor.
Every human being spends 1/3rd of their life in sleep. While many of us fail to realize its importance, it is yet one of those activity without which we cannot really do. Sleep helps in increasing mental capability and relaxes our mind and allows you to take a break.
