I'm fortunate enough to be content with the material things I have and don't need any more, so as money can't buy health, I'd probably have a fit of generosity and buy 24 hour round-the-clock adequate policing for our local community to rid it of all the yobs who run riot with their anti social behaviour, making everybodys' lives a misery. And then I'd buy a jail on an inhospitable island somewhere where they could be incarcerated until they're so old and geratric to misbehave !
