A pint a day keeps the doctor away!

So actually, at your current consumption, it's actually sort of healthy.
I would say I probably average about half that, but I don't go out drinking on the weekend as much anymore. Usually have at least two or three beers over the weekend, and usually one after rec hockey during the week. Sometimes I'll have one during the week if I'm BBQing or going out for wings.
The thing that gets me is the calories... 180 calories x 8 pints a week x 52 weeks a year is 74880 calories, and you need to burn about 3500 calories to lose a pound, so it's about 21 pounds a year you could avoid by not drinking beer at all (not quite accurate as the beer calories likely replace some other calories, but you get the drift).
