Exercise adds up to big brain boosts.

I can feel it. I know it’s bad these days to talk about IQ, but I think I’d probably do 5-7 points better an on IQ test these days than I would have a year go.

And as the article discusses, my memory has also improved a great deal. I noticed that it had declined a bit since high school, where I had an absurdly great memory (I once memorized the entire periodic table in a weekend). Since working out heavily I don’t think it’s quite back up to that level but in cramming for a certification test recently, I noticed I had to study much less than I did a few years ago to memorize similar material — about half the time.

Nice to know that the cognitive benefits accrue over time.
