“Did you know that our brains are much more efficient than computers in every way? Or that our brains have 100,000 miles of blood vessels, which is enough to circle the earth four times?

“The brain is the most complex thing in the universe,” says neurologist Marwan Sabbagh, MD. “On one level, it’s a softball-sized collection of cells, chemical and connective tissue and on another level, it’s the totality of all things.”

He shares 3 interesting facts of the brain:

1. The human brain is the only object of any kind that can contemplate itself.
2. The brain only feels pleasure and there are no pain receptors in the brain. Migraine and headache pain arise in the meninges, or the brain’s covering.
3. The brain runs on electricity, producing enough power to light a 25 watt bulb.”
