Katsuma Sameshima

Honestly, every time I think about what jockeys actually do for a living, I feel a little embarrassed about my own complaints. Katsuma Sameshima — born in 1996, still in his twenties — straps himself onto a half-ton animal and charges at sixty-plus kilometers per hour while keeping his own body whittled down to a weight most people would consider a bad week of dieting. That's the deal jockeys make: starve a little, be fearless a lot, and sync your entire nervous system with a creature that doesn't speak your language. We don't have a ton of public detail on Katsuma's biography, but the gig itself says enough. Every race is a negotiation between rider and horse happening in fractions of a second, and the fact that he's out there doing it regularly puts him in a category of quiet toughness I genuinely respect. I'm rooting for this guy.
