Do You know why humans have eyebrows? Eyebrows actually protect the eyes from sweat or rain dripping down into them, and guide the liquid around to the side of the face.
Our Brain is an amazing & highly complex organ. Consisting of 80% water, the brain only makes up 2 precent of our bodyweight, yet regulates all body functions, creates about 70.000 thoughts, and more electrical impulses than all the telephones in the world, each day. To do all this, the brain needs a lot of energy ( 10-20 Watts ) and consumes about 20% of the body’s oxygen and calories. Strangely the human brain and its 100 Billion neurons are more active while asleep than during the day & although it processes and recognizes pain from all over the body, the brain itself can’t feel pain. The right side of the brain controls the left side of the body, and the left side of the brain, controls the body’s right side.
