The brain is one of the most remarkable Organs conceivable. It is only 3 pounds in size, but has more than 30 quadrillion connections and million miles of blood vessel. Although the brain is (an energy hog) only 2% of your body’s weight yet it consumes more than 20% of its glucose and energy, and with every heartbeat 25% of the blood is pumped through the brain. This is just the beginning of how remarkable the human brain is.
