Using Indigoblue's reasoning all police officers, firemen, military members, commercial fisherman(the most dangerous occupation)and anyone else who puts himself in danger either in a form of recreation or an occupation should be single.

Interesting viewpoint.
Policework, when done in pairs, with backup, is dangerous, but not suicidal. You need to be a good shot, a fast thinker, and a cool head.
Firefirghting, when done in teams, never alone, with the proper equipment and backup, is dangerous, but not suicidal.
Commercial fishing depends on a good boat and a great crew and help sometimes from the Coast Guard, and then it is dangerous, yes, but not suicidal. You cannot control the weather, however. So it is a crap shoot at times.
In solo diving, one strand of fishing line can ruin your entire day. With the proper training, research, gear redundancy, mental constitution, and luck, it is still dangerous, and can be fatal, although it does not need to be, if only you have a buddy with you. Diving solo meets all the criteria for being suicidal.
In the military, the really dangerous jobs, like Navy Special Warfare, Army Special Ops, Marine snipers, fighter jocks, etc, is done by single guys. Guys that get married often end up with transfers to other more sane occupational specialties with promotions that pay more. That is not to say that there are no married guys in them, but when there are, their wives live lives of quiet terror while the husbands are deployed. A lot of these guys are suicidal, and I salute them. Its a job that somebody has to do.
Nobody "has to" solo dive.
