Tiger Woods told an anecdote during an interview.
"It was a practice round at Shinnecock Hills, NY, the year 2004...I'm in line at the front desk, and I get hit in the ribs. My right ribs. And it hurt. And I whip around and think I'm gonna just kill all and hit somebody. I was so pissed. I look around, and it's Muhammad Ali. And he says, 'Hey, kid.' And I'm like, why did you have to give me a love tap so hard? He was old, but it still hurt!
if he had kicked him in the crotch immediately Ali might not have killed him. otherwise even with parkinsons' ali would have destroyed him.
