Mike Tyson's age is a primary concern as he prepares to box Jake Paul, 31 years his junior, on Netflix this Friday. Tyson, 58, reassures fans that he's not only fit to compete but also rejuvenated.  Tyson makes his first professional walk since failing to get off the stool against journeyman Kevin McBride in 2005.

I want to show the world that all the sh*t I’ve been talking about beating Canelo is actually true,” Jake Paul said.
