Everybody does slow down. You look at guys like Moyer, O'Neal, Lanigan etc and they aren't at their peak anymore. They are still competitive, but they aren't the force they were. it would be hard to imagine that Bloomer's best days aren't behind him, but he'll still run well and win races for as long as he choses to race.
Time will tell if he's still at the top of the Late Model world. Whether it turns out that age and injuries have caught up with him or not doesn't really matter much to me. I'm just going to enjoy him while he's still around. He's the GOAT and the sport is better when he's around to entertain us.
