Coffee Drinkers Are More Likely To Live Longer. Decaf May Do The Trick, Too (npr.org)
Coffee is far from a vice. There's now lots of evidence pointing to its health benefits, including a possible longevity boost for those of us with a daily coffee habit. From a report: The latest findings come from a study published Monday in JAMA Internal Medicine that included about a half-million people in England, Scotland and Wales. "We found that people who drank two to three cups per day had about a 12 percent lower risk of death compared to non-coffee drinkers" during the decade-long study, says Erikka Loftfield, a research fellow at the National Cancer Institute. Participants ranged in age from 38 to 73. The association held up among drinkers of decaffeinated coffee, too. In the U.S., there are similar findings linking higher consumption of coffee to a lower risk of early death in African-Americans, Japanese-Americans, Latinos and white adults, both men and women. A daily coffee habit is also linked to a decreased risk of stroke and Type 2 diabetes.
That's how it works.

"We found that people who drank two to three cups per day had about a 12 percent lower risk of death compared to non-coffee drinkers"
Nope. I think you'll find if you run the study long enough that everyone has a 100% risk of death no matter what they drink.

selection bias. people who worry about drinking coffee live shorter lives.
I was thinking there could be some of that going on. I wonder though if its more likely to be related to other hobbies, such as cycling, or running where people drink coffee along with a physical task that involves a coffee break. So could be the exercise rather than the coffee. Would be like saying "wearing sports clothes extends your life" just because those who do athletics wear sports clothes.

The starbucks 1200 cal. coffee with all that artificial sweeteners and the sugar kills you.
A correlation is far from proving causation. It could just be that coffee drinkers belong preferentially to a more wealthy group, which enjoys better chances of living longer.
