In a purely rational world who cares. 4 months is not all that far away from 6 months and with cancer you’d probably prefer to not be alive for those last two months anyway. We should be willing to do Hail Marys with 5-10% chances of success rather than doing absolutely nothing.

You would destroy any inheritance your family might get, or which could be donated to a cause saving a dozen lives, over a 5% chance you don’t die from cancer specifically, which might make you feel unbearably bad until you DO die? Like much worse than you already feel? That’s insanely irrational.

Edit: and all of this is before the psychological implications of knowing your time is almost up. People would rather have burnt skin removed by a painful grinder than painless maggots because bugs and being eaten are so psychologically scarring most people won’t even consider it until they experience the pain of the flesh grinder work. People won’t think rationally anyways until it’s much too late.
