Brain Organ Key Ring

Cuddly Brain key ring.

FACTS: The soft, wrinkled three-pound brain inside your head is your mind, your personality and your body’s boss. From speaking and seeing, to thinking and remembering, your brain controls what you do. Can you imagine 10 billion neurons sending out trillions of messages every minute? You certainly can because your brain gives you an incredible imagination! But the brain takes a lot of energy to do its job, even just to read this card. It uses 25% of all the nutrients you eat and 25% of the oxygen you breathe. Making up only about 2% of your body’s weight, for its size the brain uses ten times more energy than most other body parts.
