Agree that there needs to be a cryonics option amounting to something like "no, but planning to sign up." I'd refrain from calling it "cryocrastinating" in the survey, both because that phrase has a judgmental tinge that, even if warranted, probably doesn't belong in survey answers, and also because it's possible that you could be purposefully delaying without it being mere procrastination -- for example, maybe you anticipate starting a job in the near future that will make it significantly easier to fund a life insurance policy.
