Floyd Mayweather is the definition of "healthy, wealthy and wise". At only 40 years old he has retired his career in fighting as undefeated and now joins an elite club.

The billionaire's club. Only 3 athletes in the world have accomplished this--Michael Jordan and Tiger Woods. Mayweather won over $300 dollars on Saturday after defeating Conor McGregor, after a 10th-round technical knockout.

He was already worth over $700 million bucks, making him the third member of the billionaires club. He had to take a ton of shots to the head during his 50-0 career--but, I think he's doing just fine with that billion dollars!
