I finally signed up in 2016 as well. It is The Responsible Backup Plan in the grand scheme of things, assuming you are someone who likes to be alive. Around that time I set down some high level notes on what I think to be important in the process, which can be found here:

"I have put off signing up for cryopreservation for a decade or so. This isn't uncommon; after all, it involves paperwork, adult responsibility, planning ahead, thinking about unpleasant events, and all that. People put off many other things for these and similar reasons. Writing wills, buying houses, getting married, starting companies, and so on. That doleful feeling of some unknown scope of paperwork that will have to be accomplished in the event that you do get your act together and set forth to be a responsible adult is ever a strong deterrent. Still, sooner or later all these tasks have to be carried out, and while no-one enjoys wading through legal documents, it is never as bad as you think it is going to be. If you are unfamiliar with the process of signing up for cryonics organization membership and cryopreservation, let me tell you that it is much less work than buying a house. It is about two and half times the work of getting a life insurance policy, if that helps calibrate things any better."
