astronauts? I can't imagine anything more claustrophobic.
Lazy, maybe you should watch "Jeremiah Johnson".

I seem to remember reading something about how ceiling height affected perception: lower ceilings => more precision and analytical attention to detail; higher ceilings => more flights of fancy and expansive thinking.. something like that. I sure know that I do feel cognitively 'lost' in my high-ceilinged Italian house compared to my low-ceilinged NE homes, but it's hard to separate out other factors from that. OTOH when I am out and about I definitely notice the different feeling I have living now in a small hilly area with no view of any real horizon, versus the relative plains/oceans I was used to.
