From that we learn that coffe is linked to increased levels of smoking and lack of exercise -- AND:
A May 2012 study by the New England Journal of Medicine found that, during the course of their study, coffee drinkers "who drank at least two or three cups a day were about 10 percent or 15 percent less likely to die for any reason during the 13 years of the study."
That combination seems to imply that coffee in itself is healthy.
Besides, we Scandinavians drink the most coffee on the planet and we are are are are healthy as He He He Hell, but a bit twitchy. It is a totally false rumor that we die if our blood turn red.
Edit: I should add that no chemical is good for everyone, not even caffeine.
