From Science Daily:
Regular coffee drinking (up to 6 cups per day) is not associated with increased deaths in either men or women. In fact, both caffeinated and decaffeinated coffee consumption is associated with a somewhat smaller rate of death from heart disease.
Does six cups per day seem like a lot to anyone else? I'm admittedly a lightweight, averaging only about 2 - 4 cups per day. Of course that number would vary wildly depending on how many breakfast meetings with John Warner are scheduled in a given month.
