How much space do we need? Does space affect our feelings for one another both inside and outside our personal spaces? Do some cultures have no concept of personal space? Alone, I imagine I could live in a relatively small space. I once lived for two months in a tent on the back of an 1963 International Harvester 3/4 ton pickup. With each person sharing that space, the need changes or one's concept of solitude changes. You make an excellent point about access to outdoor spaces. Right now, I have to get rid of stuff, lots of stuff. If you spend your first 50 years collecting stuff, you spend the next 50 trying to get rid of it.If it doesn’t rain, the parks are filled with people sitting, walking or jogging around.
When I have access to outdoor space, everything feels roomier; however cold, dark, and rain will make us feel more crowded. Attitudes about needs and space probably depend on how much roaming space you have inside your mind vs how much external stimulation you need.
