I'm 49 now and stopped when I was 47, 1.5 years ago. I have no idea if I have "gotten away" with it but I honestly never think or worry about the damage that I might have done to my body these days. I'm living really healthy now and I can't do more than that. Note that I did feel like crap the first weeks of being sober with odd pains and aches - I think it was just the body getting used to it. Virtually all of my health problems these days are sports injuries :-).
