You've heard of life insurance, but how about death insurance!
While life insurance insures you against death, death insurance insures everyone else in the unfortunate event of your survival.
Really hate someone and just waiting for them to die? Want to get paid for having to deal with them if they hang on a bit too long. Get death insurance today!
@freemo loosely related: Did you know that in France, you can acquire a house by paying the owners a pension until they die? If you're into gambling or "accidental" deaths, buying a viager is for you: https://www.investopedia.com/terms/v/viager.asp
@mjambon Interestingly enough there was a boom in the blackmarket assasin trade right around the time these laws were passed :)
