To Have or Have Not.....Post-run Beer?

Whenever I finish a race, I have never understood the people who are physically capable of drinking a post-run beer. My mind, body, stomach....everything.....tells me this is a horrible idea. Sometimes this makes me super sad, like when 312 hands out a complimentary beer at the end of the Chicago Marathon, or when O'Fallon Brewery shows up to local races and gives out samples to the runners after the race. So, the post-run beer....good idea or bad idea? Obviously its a personal thing based on your body and how it reacts to intensive physical exertion, but here's a link to a more in depth discussion: http://fitbie.msn.com/get-fitter/whats-harm-postrun-beer
