There is some literature showing kids who learn chess learn other stuff faster, but over time the effect dissipates and they later regress to the norm. Older people can fight off dementia by playing chess or other thinking games.
Sorry, you should play the game if you enjoy it and want to improve at it for more fun, not because it will improve your brain.
If you want to improve your brain, you should try drinking lots of craft beers and chasing after busty bar wenches. It won't improve your brain any more than chess, but your disappointment will be soothed a bit.
Post of the week.
I could not Possibly agree more!! -- My only caveat: the omission of "beautifully built pool boys" as an optional alternative to "busty bar wenches."
Hey Sigmund, we're childhood friends! Remember me?...
