Mike Tyson, former world champion, has spoken out about his age.
"We don't know how old we are. People create their own calendars. The biggest flaw in a man is the belief that there are limits. I don't believe I'm 58 years old, I don't feel that age. I fight the big guys in the gym, the young guys, the 30-year-olds. They don't get anything," Mike Tyson said.
