It's the letting go of the sport maybe makes it really harder. I agree that he might be in danger in a way just because of the blows to the head that could incur more injuries and he might not be coming back anymore. I think he needs to think far ahead of his future and what he is going to do.
Did you know he's also a multi-term senator (currently in office), professional basketball player, actor, and has a good shot at being president some day? I'd say he's already accomplished quite a bit, however you're right in that who knows, maybe he's only a concussion or two away from triggering some long-term cognitive problems. I could point to Mayweather as a man who still boxes despite being older than Pacman, however Mayweather dodges a lot of punches and that could be adding to his longevity.
