Serious deja vu -- have we had this conversation before?
I don't see the appeal, I do see the unnecessary rough treamtent of horses, as well as the brutal self-abuse that jockeys do to keep their weight down.
Watch the documentary Jockey, it's been on HBO for years. They're more fucked up than supermodels. They all puke, and take laxatives, and sit in steam boxes for hours, and ruin their livers, kidneys, skin and teeth in the process.
It's one of those vestiges of what I call "Old Earth" that I hope will fade away in this century the more we evolve (or Republicans die off, same difference).
