Perhaps it's who I know, but I know more athletes who've required extensive, expensive, knee surgery than morbidly obese.
If there's one thing that has policymakers and actuaries in a tizzy these days, it's how to contend with the costs associated with paying for all of the knee-repair bills for amateur athletes.
It's actually kind of flattering when people who can't address an argument intelligently, let alone refute it, elect to respond in this fashion.
