Coffee helps people live longer.*
In previous studies somewhere it looked like it was bad for you, but in this study they factored out other things that tend to go with coffee drinking, like smoking and some other stuff, whatever, and it turns out the more coffee you drink, up to a max 4-5 8oz cups, the better it is for you. Or something. I was too busy going "whee! \o/" to read it really closely.
Now to install that pipeline from Tim Horton's...
*(Tea does too I'm sure, it's no doubt even better for you than coffee, but the study was coffee-centric. Sorry strict tea-drinkers, but take it as proof that no one's worried enough about tea being bad for you to commission a study into it?)
