It decreases the blood flow.

So...

I think it's a really interesting topic, and it's something that should be investigated.

It's kind of hard to investigate.

This was a story that occurred early on in our investigations when we first made the discoveries that cooling has a benefit to increase your work volume, your capacity to do more reps.

So the word got over, I think, to the 49ers camp.

And one of their players, Greg Clark, who was a tight end at the time, he had been tight end at Stanford, he decided to come over and check it out.

So, Greg came over and we said, Greg, what are you good at?

What activity do you like to do?

He said, dips.

I can do a lot of dips.

I can do 40 dips in a first set and I can probably do five sets.

That's a usual workout for me.

And we said, okay.

So he came over to the gym one day and that's exactly what he did.

He did 40 dips, the first set, and then maybe 25 and 15 and down from there.

Can you recall roughly what kind of rest periods he was taking between sets?

So several days later, he came back, and his first set he did, I think, maybe 42.

Then his second set was, I don't remember the numbers, but very much above the second set on the control day.

This was after we cooled his armor surface.
