Looks Easy, Huh?
This "Hollywood" spacesuit weighs about 60 lbs. It's a Hollywood spacesuit because it's not actually real, it only has the same demensions as a real suit. Lucky for us, because the real things weigh A LOT more.
The only reason Data is smiling is because he is being supported by the metal stand around his waist.
Tomorrow, I will be wearing one of these (all the weight supported by your shoulders) for 2 hours at a time. I think I might die.
