Hey folks, it's Ben Greenfield and the guy who's on the call with me right now is one

pardon the expression, bad ass old dude.

So his name is Mike Greer and I first met Mike at the Become Superhuman Live event.

And he kind of wandered into our morning workout and pretty much proceeded to destroy

a bunch of fit young guys and girls at burpees and lunges and push-ups and Turkish get-ups.

And he was decked out in Iron Man gear and tanned and I figured he was one of those kind

of 50-some-year-old triathlete workout enthusiasts.

But it turned out that he's 75 years old.

As I got to know him, not only did I learn that you don't even need to call him Mike Greer,

that most folks just call him Greer, but the guy has done a ton of things.

He's an entrepreneur who started over eight different businesses.

He had a military career.

He's a retired lieutenant colonel.

He was a football player.

He's a seven-time Iron Man triathlete.

He's been the past president of the board of USA Triathlon and he's the president of

the board and the CEO of the Obstacle Racing Association.
