What Caffeine Actually Does to Your Brain
No discussion of coffee's many (many!) health benefits? [men.webmd.com] Cuts your risk of liver cancer, cirrhosis, Parkinson's, diabetes... for the most part, the more you drink, the more benefit you get, and according to most research, it's at least partially the caffeine that is responsible. @MrsButterworth: Wasn't really in the scope of what I was writing about. It was aimed at caffeine, specifically. @Kevin Purdy: Oh yeah, sorry, I meant "no discussion so far in the COMMENTS..." since everyone is talking about how much (or little) coffee they drink and why. Although the Parkinson's connection is another way caffeine affects the brain, albeit in the long-term.
