Percentage of people that make it through SEAL training is about 20%.

People that are under the age of 20, it goes down to about 5%.

So, yeah, I was one of those like small percentage of people that are very young but still make it through.

They try and simulate hell.

It's...

They actually were trying to simulate combat initially.

When they created that week, they wanted to take as much combat simulation from World War II at the time and put it into a very compressed schedule so they could create these frogmen to go overseas and conduct operations because World War II was going on.

And so they needed to compress the training cycle.

So they compressed a bunch of that combat simulation into... It's about five and a half days...

No sleep, lots of physical activity, lots of stress, lots of pain, and lots of people quit.

How many people quit in that particular week?

I would say most of the people that quit, probably 80% of the quitters quit in that week.

There's some internal drive that you either have or you don't have.

And if you have it, you won't quit.

And if you don't have it, you're going to quit.

And it breaks people.

The other thing is you might be an exceptional swimmer and you might be exceptional upper body strength, but you're not that fast of a runner.

They're going to find that out.

Or you might be a fast runner, but a bad swimmer.

They're going to find out what your weakness is.
