After living thru the COVID lockdowns, WoBG and I were both more than happy to go for walks, ride a bike, or go just about anywhere rather then stay inside our home.
I can't imaging being inside a small spacecraft for weeks, month, or worse years.
I think more than a few people could become selfish, paranoid, mean, insubordinate, not a team player at all, etc... on a long space voyage in a spacecraft.
@maddmaxx I'd guess some crewmembers on a submarine on a long deployment can become stressed, etc... ? Was that a problem for some?
