Caffeine and the Brain

Over at Lifehacker there is a really informative post about what caffeine actually does to your brain. Basically, it prevents your brain from slowing down. It isn't actually a stimulant, but a de-depressant. Also, you get acclimated to it pretty completely, so that it doesn't affect you anymore, except when you don't have it. Sigh. Still, it's a great addiction to indulge in on a rainy New York day like today.
