Rehab is worthless beyond worthless. I liked Audrey Murphy's strategy, of locking himself in a room for a week, far better.

Rehab doesn't address the part where you come back to normal life. And all the old aches and pains start up and nothing seems worthwhile and there's little work...

Teaching the homeless to be COMPETENT nomads is a better strategy. Otherwise they're at the mercy of public officials and contractors who only see them as a flesh to money machine.
