Sam,
Physical should not be an issue - I think good cardiovascular
health is sufficient for us. The standard flexibility and upper body strength etc dont
matter in space, everybody is about equally strong and flexible there! Why, I could resist Arnold there! This is in space. On the moon, the equations change again where we have 1/6 of our gravity. Yes, it will hurt less on the moon! Let me book a seat if we ever organise a KA space program!

Of course, we dont stand a chance in a regular astronaut physical test, it takes very tough people on the planet to qualify. I heard Russian astronauts have to pass a shock test, where electricity is passed thru the body for around 2 minutes. Anyone gutsy here?
