curious do they hang their laundry on the exercise bike har har just kidding,

seriously though isnt the exercise program helping them keep more bone mass while in space for longer periods of time, not saying toilet is more important or not, but I was under the assumption the exercise program was a must for long term space trips? for bone mass issues

ok reread your post again i think i got the drift, i take it when the toilets broke down last month they were not as concerned as they are about this treadmill
