A few years ago, maybe still, life settlements were the latest fad to be heavily hocked on AM radio. About every 5 years my wife hears some financial scheme on AM radio and says I need to look into it. (Others included various annuities that ended up having terrible returns, or advisers who had some sort of trading scheme, which was really a glorified moving average scheme, which ended up giving horrible predictions).
Putting aside it's kind of a icky investment, the faster the original beneficiary dies the better you do, their returns apparently were greatly exaggerated.
