Chrissy is literally doing nothing of value with his time, and yet feels fee to moan about how other people use their time.
Dont forget all the times he stops and poses for selfies either.
On a deeper level when Chrissy says he'll never get to the point of walking slow I think he knows cancer/stress/steroid abuse/heart attack will catch him before he gets to 60.
Shot at a park for being a creepy creeper is a possibility too if he isnt careful.
