They do work out in space to keep their muscles from deteriorating.
There is NO WAY you can come back and this has no neagtiv effect on you at all. We talking about 20 years in zero gravity or at least the gravity of the moon, wich is only round about 17% of earth gravity. (Heart, Bonestructure and Loungs are effected too)
In my opinon, this guy should lie in bed, with maschines helping his heart an loungs. After his bodyfunktions are working fine, he has to go to rehab, so his muscles getting trained.
Maybe its to realistic but i think he should at least lie in bed or sitting in a wheelchair and not standing there like he was back from a vacation in the next door country... ╮( ˘ ､ ˘ )╭
I understand that he just came back, not that he is back for over a year or so.
The mental issus should be the last of his problems right now.
I didn't say he'd be completely fine, I was just saying weakness wouldn't necessarily be his problem. I don't know what's going on with the rest of the body after such a long time, but astronauts do know how to prevent muscle atrophy with specific resistance exercise. After getting used to the feeling of gravity again and finding their balance, astronauts can walk just fine after coming back from space. However, nobody has ever been in space for 20 years, so who knows.
Yes, BUT it takes time. Like i said, it sounds to me, he just came back. Thats my problem.
...this guy was 20 years in space? I just want to point out that i am not sure, if this man could walk after all this time. Because his legs would not be strong enough after 20 years in low or non gravity...just saying. ╮(￣▽￣)╭
And i don't know how the rest of his body would handling the pressure of earths gravity...
