To practice on me before something happens to your female family members and you've got to convince them...

Are you such a Platonically ideal female that we can generalize from you to other females, who may have expressed no interest in cryonics?

Friendly hint: you just implied my life isn't worth saving. I am not easily offended and I'm not hurt, so that's just FYI.

If you see it that way, it sounds like you're already very nearly convinced.
