Exercise is really, really good for your brain

Physical exercise is good for your brain. And I mean really good for it. The brain burns a ton of energy during exercise, much more, even, than if you were thinking really hard about something really complicated. New research has discovered just what the brain does with all that extra energy.

"From a metabolic standpoint, vigorous exercise is the most demanding activity the brain encounters, much more intense than calculus or chess, but nobody knows what happens with all that energy," says the paper’s lead author Richard Maddock, UC Davis research professor of psychiatry and behavioral sciences and affiliated faculty of the Center for Neuroscience.
