I think that letter's fine, A-OK. People write much mushier ones to Nascar "heroes", baseball and football players, etc., and are not sick, they just need something or someone to believe in, "if they can make it, I can make it' kind of thing, and it honestly helps them out. The OP went from a depressed, probably out of shape, mopey person to a guy who races and has 7 bikes. That's great! Is having "LIVESTRONG" tattooed on your leg somehow dumb while all the other stuff you see in tattoos, not? Give the guy a break! Lance is a good old fashioned role model and those are rare these days.
