My wife thinks cryonics is disgusting although she has promised to call Alcor if something bad happens to me. My parents and sister are fine with it. My students are shocked when I reveal it to them but respond with laughter.

I would consider my life to be significantly worse than it is now if I had to sever a lot of these emotional ties.

Perhaps those of us who have signed up for cryonics should get to know each other.

I'm not particularly good at forming new relationships, and I'm very worried that signing up for cryonics will create an insurmountable social stigma that will make it nearly impossible for me to do so.

You can keep it a secret. Chances are if you die you will know ahead of time so not wearing the neckless/bracelet won't greatly reduce your odds of survival. Also, think of cryonics as peacocking.
