Answer 1

1.Your brain weighs about 3 pounds. Of that, the dry weight is 60% fat, making your brain the fattiest organ. 

2.Twenty-five percent of the body’s cholesterol resides within the brain. Cholesterol is an integral part of every brain cell. Without adequate cholesterol, brain cells die.

3.No one knows for sure, but the latest estimate is that our brains contain roughly 86 billion brain cells. 

4.Ninety minutes of sweating can temporarily shrink the brain as much as one year of aging.

5.Your brain is 73% water. It takes only 2% dehydration to affect your attention, memory and other cognitive skills.

6.A piece of brain tissue the size of a grain of sand contains 100,000 neurons and 1 billion synapses all communicating with each other.

7.All brain cells are not alike. There are as many as 10,000 specific types of neurons in the brain.
