Is he some sort of hobo philosopher a la Diogenes, sharing his insights? An ascetic monk, deep in meditation whenever he's not working and wanting for nothing? Idk, it didn't seem that way to me. I'll give you that he leads a very ecological life, but it seems to be more the result of poor financial choices. Maybe he's working this hard to give it all to charity every month, who knows? But I bet that's not what's happening (probably gambles or drinks or smokes his money away), and as such this is just a sad and aimless life.
