No,no,I'm not going to stop sleeping!I find it something wonderfull,but I was wondering what is the purpose of sleep biologically...
Why does our body needs sleep?Why and how does it asks for sleep?I have heard something for rejuvenation of brain cells
Is there anything else?
Asking in another way:
Serum can take the place of food for a while.What would do to our body a theoritical 'serum of sleep'?!
