I didn't know him before that.

But

At the end of the day, I was very fortunate to go down through Boot Campaign, through Morgan Luttrell, Marcus Luttrell's brother, and went down to see Dr. Hart.

They took three of the Nitro Circus crew of us that had the most concussions and went down through it.

And what was the most fascinating part through the whole thing was that

There's not really a template for what a human body can take, and every human is very, very different.

So Dr. Hart said, think about your family history and think about, for example, anyone that's made it in a contact sport.

Chances are, is predispositioned to be able to take a hit.

And he's like, I have patients that have had 50 plus bad concussions, minutes unconscious, that are still at seven years old, the sharpest humans you ever met.

And I've had people that one concussion, not even fully unconscious, changed their whole personality.

So he goes, look, we have.

So he's kind of the one that sets for U.S.

government like, oh, you're supposed to take X amount of time off.

He's like, I've had people that could be knocked out for 15 minutes that I would approve to go back out there and get right back to competition.

And I've had people that, after a mild concussion, I would not approve after a year.

So he goes, we have to set guidelines on it.

And he goes, the guidelines are to save the athletes from themselves.

Because every athlete, and I've done this before where...

I'll, there's video of me saying, no, I'm perfectly fine, I'm good.

I don't remember racing that race, I don't remember racing that race.
