coffee != caffenine so stop comapring it to coke!
Al that soda etc is nasty, thats also got a shitload of sugar in it and phosphoric acid. Also coffee can be consumed cold and thats how i normally have it, ie iced coffee, wihch basically just menas more milk to form sort of a cafe latte' or whatever its called.
NOTE: for the non-geeks, != means does not equal
ahhh too much C for me today... sigh
