 It is part of also the fact that you're in a very, very small aluminum tube in some cases. So it is very stressful on the body. If you've ever had a bad roommate, anyone can attest that it's not pleasant. You'd like to get out of there, but there's no way to get out of there. So you are stuck in that capsule, and there's nowhere else to go. So you can have entertainment options. You can do workouts. You can live reasonably well, but it is a very confined space.
