>>13012387Being smaller actually makes bumping easier. "The bigger they are, the harder they fall," and all. It's just in Bryan's case, he also takes some of the craziest bumps in the business, so being smaller doesn't help him.
His diet probably doesn't help, but I the real killer for him is that he's not very naturally athletic. He's much more athletic than, say, Phil. But he's still a regular guy who, though he keeps in good shape, pushes himself through Bruce Waynean abuse. Except he's not a jacked, 6'4" billionaire who doesn't age.
