Hurricane forced NASA bedrest volunteers to stand up early

Dale says:
Folks in a NASA study ... were actually supposed to spend 90 days inclined at an angle of -6 degrees (with their heads lower than the rest of their bodies) to simulate the effects of microgravity. But last week they had to end the study early because Hurricane Ike was headed straight for them in Galveston, Texas.

One of them had spent 78 days in bed.
