Did you know doctors study sleep just for 2 hours in med school? Just 2 hours for something that takes up one third of our life. Quite disturbing.. So if you want to know more than they probably do about sleep, go ahead and watch this clip, it's definitely one worth seeing or listening to while you go around your other online activities.

Some things I found interesting:

Night shifts have been classified by the World Health Organization as carcinogens.

All of us have bad cells growing inside us every day, but when we sleep the body takes them out to trash. 

People who sleep less then 7 hour per night die younger. Not sleeping is like borrowing life from the future.

Let me know what shocked you.
