Almost all of us have played in those kind of games, you know, or grew up in that kind of weather, you know.

And bottom line is, I mean, these guys are young, they're healthy and their heart pumps, warm blood.

It pumps it from the arteries to the veins, to the tributaries, to the

capillaries, you know, throughout their whole body. You can just play ball. It's been my experience.

I've got that in the wrong order there. It's well documented. I'm not a got that in the wrong order there.

It's well documented. I'm not a doctor, but I know it's warm blood.

Young healthy athletic guys are able to generate. Jim Harbaugh, not a doctor and did not stay in a Holiday and Express last night.

It's PFT Live, presented by Accenture.

I don't know that tributary is one of the vehicles that takes the blood from your heart to your outer extremities.

And all of our hearts pump warm blood.

If they don't, you're a vampire.

So it's a given that we're all pumping warm blood.

It's a major problem if you're pumping cold blood.

But when you're out in the cold, it makes everything cold.

And it is a state of mind, Rodney.

You've played a what the hell are you

talking about it. I'm talking about what Jim Harbaugh just said. Were you not listening?

He's a smart guy. I have no idea what he's talking about. He's a very smart guy. A tributary is a

river or a stream that flows into a larger river or lake. It has nothing to do with the blood system.

And I think it's the vascular system.

I'm not a doctor either in the human body.

But it is mind over matter, right?
