 Good. I'll cut you off if we're too long. So here's the deal with blood oxygen. First of all, let's just talk about this little thing. It's a little clippy thing. It's called a pulse oximeter because it has a pulse on it as well. It goes on the tip of your finger. You hold it there for five seconds or ten seconds, and you look at it, and there's a number that shows up. And that number usually is for the oxygen. Forget the pulse for now. The oxygen saturation in the blood. It's 90-something, almost always. Almost. Yeah, and it's 92 out of 100, right? Right.
