How long will you live if you drank beer for forty years?

If you've drunk beer for 40 years, and you started when you were 16, you've probably gained extra weight and have strained your liver. But of course this depends on how much you drink beer. If you have one beer everyday your entire life, you could live forever with no damage done to your body. However if you've been drinking 3 or more everyday since you were 16, your chances of having complications in your early retirement years are high.
