Vitor Belfort made his UFC debut at nineteen years old in 1997 and sixteen years later is still fighting a top level and maybe the best he's ever been. Now thirty five years old, Belfort shows no signs of his age and if up to him, we'll see him in the Octagon for as long as possible:
"I believe in joy," said Belfort. "When I step into the octagon and I don't feel the pleasure and I don't feel the adrenaline and the purpose, I think it will be time to stop.
"I made a plan to go into my 40s, so that's kind of the plan. So I like to plan things. I believe the more you plan, the more you succeed."
