Not the old people with cancer or parkinsons, or going deaf, or really old people in general. They can't wait too long.
Anyways...I'd say Ali's punches had more effect on Ali because George was exhausted and litteraly stepping into Ali's punches. Stepping into them hurts. I know from personal experience. Walking smack into even a light jab hurts like hell. Walking into a hard jab hurts worse (obviously). Foreman was walking smack into Ali's punches face first, and he was exhausted. So it increased the pain and effect of Muhammad's shots.
LOL. Who knows? He was popular back in the day. I wish he still was. He was the first guy I payed attention to. He's still tied for my 1st favorite fighter of all time.
