Good grief this thread is a miserable read.
Personally speaking, it is wonderful to admire great performances without holding an assumption that winners or high achievers must be cheating. Yes, some people cheat in all walks of life. It isn't new and it is a minority. I'm delighted to find my own response is purely admiration for great sporting achievements, unfettered by that bothersome, muttering cynicism that seems to burdon some other people when they watch top level sport.
