Guy at work that talks shit about the lunch I bring every day instead of ordering bullshit said some shit like that one day. He was performing for the small fat audience that happened to be around us and running his mouth saying things mockingly like "His body is a temple" with the flourishing hand motions and all. Then he goes, "Whatever, he'll be fat in ten years anyway."  I said, "Only if I totally give up on my health..." with a purposeful look at his gut, "and besides, you know I'm older than you, right?"  Cue shock and awe when they find out the fit guy is already 30 and looks young because of quality nutrition and exercise.
