For that we'd have to get into QALY's which is tough since we can't make any kind of reasonable estimates for how many QALY's someone would gain (perhaps future government decides to deal with a population crisis by setting maximum year limits).

Micromorts aren't perfect but do make it possible to compare because 1 micromort suffered today can be used to judge cash value something is worth. If you'd accept a minimum of $10,000 to perform a 100 micromort task today(making you quite a bit more cautious than average) that still reduces your chances of immortality even if you're signed up for cryonics which allows you to do some kind of cost/reward tradeoff calculations.
