 Okay, so we talked about what happens when you go up, but what happens when the astronaut comes down, certainly in line with what we would expect. Definitely, the preload goes down as gravity pulls blood into this expanding volume that now exists. If it's pulled down by gravity, the preload goes down, as the preload goes down, there's obviously a decrease in struggle volume, so we're going to go back to about 70 or even less milliliters per beat that gets ejected. To compensate and maintain an adequate colleague output, you're going to increase the heart rate. The blood pressure is certainly going to go down, especially when the astronaut tries to get up, there's certainly going to be some orthostatic hypertension. Now the ADH will go up, this time it's not only because of the stress, but also physiologically as we might expect. The body now realizes there is not enough fluid or plasma volume or water to go around and it wants to conserve that, so this will go up to about three times increase. Renin activity will go up to about four times increase. We're going to get increased aldosterone levels because of that, about 50% increase in those levels. Atrial-natriuretic peptide, that is going to decrease by about a third. All of these things are easy for us to explain. Certainly the fluid intake is going to go up, as we would expect, and the urinary output, well the urinary output is actually going to decrease because of all of this, but it's decreasing relative to what it was before the flight. Certainly going to be a bit more than it was during the flight when it is especially low, but certainly the urinary output will decrease as compared to before launch under that 1G condition.
