Peter Sagal's Thin Line at Runner's World

Peter Sagal's Thin Line at Runner's World: "Mirrors are not to be believed. You stand in front of them, knowing that you can't trust yourself as an arbiter of truth, so you turn from side to side, thinking that maybe, if you snap your head around quickly enough, you can actually see yourself as others see you. It never works, of course. You stare and you turn, and you wonder: Am I fat?"
