Can Aerobics Make You Smarter?

This article in Men's Health points to studies linking 30 minutes of aerobic excercise three times a week to mental performance. This is the first time in my life I've ever been seriously tempted to excercise. I doubt that thirty minutes of jogging would cause me very much discomfort; that's point one. If I got an .MP3 player and listened to podcasts (and especially a voice recorder with clip microphone), I could avoid the boredom that has always deterred me from excercising; that's point two. But as with any endeavor, it's not the cost but the benefit that entices, and in this case that's now point three. I have no shortage of ideas, only a shortage of time in which to implement them, but this article describes how that ratio is somehow paradoxically improved by spending a little time on cardio. The description of excercise as making me less distracted is tantalizing. I've never sat there thinking "if only I were more intelligent and creative," but hey, I don't think there's too much of a good thing where these are concerned. What more might I acheive? I certainly don't need to get smarter, but I might benefit from being more "focused" or perhaps even more "driven." Is excercise the key to fame and fortune? I'm sure I can get an OK pair of tennis shoes and a sweatsuit at the thrift store. Hmmm... maybe I'll do this.
