Sleep: Post #1--Brain Nutrients and Waste

The Importance of Sleep
One more reason to get a good night’s sleep. ~Jeff Iliff (2014 TED Talk) Summary


Brain Nutrients and Waste--Sleep is an elegant design to solve one of  two problems that every organ in the body has to solve: 1) How to get nutrients to the organ and 2) How to get waste away from the organ. These are especially important tasks for the brain, which is only 2%of our body mass but uses 25% of its energy.
