As others have said, that option is no longer available. I don't find it as bad as you do though, for three reasons:

• She's a relative, not a stranger, so this kind of discussion would have happened anyway if I'd cleared my cryonics cache before six months ago

• She has reasons to accept it that she accepts; the problem with a lot of religious conversions is that the only reason I should believe in the religion is because it says to and anecdotal evidence; for cryonics, the reason to believe in it is the standardly-accepted science and evident technological progress, both things most people at least claim to accept, but without any anecdotal evidence that it works.

• I am disgusted by people who think that something is that important but don't do anything about it. My standard example is vegetarians who believe that animals are conscious sentient beings whose death is as tragic as a human's, but don't attempt to persuade others not to eat meat. Of course, if they did persuade others, everybody else would be annoyed, but if they're committing murder and you can get them to stop, you should. Similarly, if somebody is dying and you can potentially stop them, you should.
