I always get a kick out of articles whereby they basically say 'hey, excercising is good for you!', as though that were some kind of new discovery :) This is a good article, and as others have mentioned it actually links to scientific study, which is a rarity for mainstream press. On the other hand does anyone here think that getting regular excercise WOULDN'T be better all around, in a multitude of ways, than say sitting on your ass all day?
Invariably on exercise-related articles there will be a comment saying, basically, "Congratulations, science, for proving the obvious..."
The proper response is always the same: even what seems intuitively obvious needs continual verification through the scientific method, both to understand the underlying physical mechanisms that drive a phenomenon, and to detect situations where our intuition is wrong.
I have quite weird view on physical exercises, so for me seeing why it work this way and understanding what is going on in the brain during work out helps.
