"But just because I'm fit now doesn't mean I'll always be. And just because I'm fit now doesn't mean I'll continue to be fit, to be able to play. There's more to it than the physique, it's... it's the endurance and reflexes and strength and speed and-... And... balance. It's everything. And maybe, by the time I get back, I'll be fired. They'll have found someone else, someone better, someone far more fit than I am."

Another run. Another swim."
