As I mentioned in a private message to Hallquist, I favor a wait and see approach to cryonics.

This is based on a couple observations:

1. There is an excellent chance that when (if?) I die, it will be either (1) in a way which gives me enough advance warning so that I have time to sign up for cryonics; or (2) it will sufficiently sudden that even if I had been signed up for cryonics it wouldn't have made a difference.

2. It's not too hard to get cash out of a life insurance policy if you are terminally ill.

So it seems there isn't a huge downside to simply carrying life insurance and waiting to make the decision about cryonics. From an actuarial perspective, I have a pretty good chance of living another 30 or 40 years so there is also the possibility that more information may come out helping me to make a better decision.

Edit: As I mentioned to Hallquist, I am a bit concerned that my argument is basically a rationalization for cryoprastination. So feel free to point it out if I am missing something important.
