I personally think money. If it’s the toughest and dirtiest maybe theres a large income. It could also be that people like the thrill of danger and want to experience new situations. For me it would be the money, if they are making people do these jobs it must have a reward involved. As I said I could be wrong though, maybe people just like being wild. Maybe they like being dirty, and working hard. It all depends on the person and what their personality is.
