It's the largest ever study on coffee and longevity, and it's found that an extra cup of 'Joe is not a bad idea if you want to hang around for a while longer.

FOX News Radio's Chris Foster has more:

It can't prove that coffee makes you live longer, but this study of 400,000 people finds hose that drink it are less likely to die - 5-or-6% less likely in any given year for one cup drinkers, up to 16% for women who have four or five cups a day.  That survey, conducted by the National Institutes of Health and the AARP.

The researchers adjusted for other factors that could throw off the results, like smoking, drinking and exercise habits.  Doctors do say, though, watch the sugar and cream.
