How many different brains were involved in making it possible for you to read this blog entry? Whew! That's a tall order to even look into!
Think about all the amazing things the human brain has done, yet it's a pretty small organ. The brain takes up about 2% of your body mass, that's it! Despite its small size it sure does carry out a lot of vital functions that keep you going — such as: breathing, eating, walking, thinking, sleeping, sitting, showering, brushing your teeth, and so on...
The brain also uses up about 20% of the oxygen we take in!
On average a human brain is about 77% water!
The brain also works on about 20 watts of power (the same as a laptop or the bulb in your fridge)!
