I worked in an office that was right beside a homeless shelter. I found there were usually three types, A) mental issues, B) drug/addiction issues, and C) people that actually like the lifestyle. One older man's wife had died, and he gave everything to his kids and went to living homeless. The guy told me he loved it because he considered it absolute freedom.
