While living there, I swore to myself I would never live in a trailer again and stated "I would rather live in a tent." Which I did, in actual fact, do for some years at a later date.
I got healthier while sleeping in a tent and desperately poor.
Doctors used to take their little black bag and do house calls. This allowed them to know a lot of things about your life without asking and to factor that into their diagnosis and treatment.
I think medicine is worse off for no longer doing that and I think Sick Building Syndrome is much more prevalent than people realize.
