While it is fairly well known that exercise provides cognitive benefits, I think most people would be hard pressed to explain exactly what those benefits are. I was sent this handy graphic that does just that.
So next time you find yourself being lazy and uninspired, think of how much better you could be doing if you just got some exercise. This goes double for any kids you may have. Unplug that TV, turn off the video games, and ship those little people outside to work up a sweat!
