If you don’t expect yourself to go through the full process right away for whatever reason, but you want to increase your chances of cryopreservation in the event of your death, you should do the following two easy things:
Become an Alcor Associate Member (application form here), which costs $5/month, plus a $60 one-time application fee
Taken together, these constitute informed consent, making it much more likely that it will be legally possible to preserve you in case of an emergency.

ah, I see! yeah, I guess being an associate member is stronger evidence (but am almost certain some people were preserved without this)
