He'll probably wind up a frozen mummy to be discovered 500 years from now.
I was in San Diego some months ago for a conference. I overheard a conversation between a young guy setting up tables at an outdoor restaurant and a 'hobo' in the neighborhood. The hobo was trying to talk the young guy out of working and just live off the streets.
The young hispanic kid just kept working. Hope he does well.
