That may be so, but in my old age I find it makes me feel better, not worse. And I don't get sick much anymore, I did more when I was younger.
I have a friend my age who has a ritual -- every night when he gets plastered, on the way home he gets a chicken parm sandwich and a quart of milk, and while he sometimes passes out before eating the sandwich, he downs the whole quart of milk without fail. He never gets sick.
Then again, I'm starting to think he's a vampire. He also has the same body he had when he was in his 20s...it's just not right...
