Homeless go back to being homeless because it is what they are used to

Here is an incredible story of a homeless fellow trying to go from living in a cave he created to living in an apartment.... Old habits die hard, it's impossible to take someone farther than they can see.... I can identify with parts of the story. I escaped California's sky high rental market for a few years by living in an RV. It was a fun time, nice to save $1000 or more a month. However, I still have a habit of scanning for good places to pull over for the night, or looking for electrical outlets in parking garages that I might plug into..... For someone suffering from mental illness, and drug addictions, they may have lost the higher brain functions that would allow them to override the animal like tendency to live according to instinctual responses.
