I'm not sure how I'd do with being confined like that. Used to, several years back, it wouldn't bother me. Now? I think it would take a toll. Sorta like, I wouldn't mind being a guest on a submarine for a day or 2, but I think I'd have a meltdown if we couldn't surface for 5 months. After some recent (out of nowhere) issues with mild claustrophobia in the last couple years, that sounds like a nightmare.
