Well ... isn't it? What others are you thinking of? None spring to my mind.
Upvoted, but I think you misinterpreted the grandparent slightly.
If you don't sign up for cryonics, you will have no chance at all of coming back if you die- the claim is literally true - but the grandparent seems to be considering the broader class of "might hopefully delay (or prevent) death" - anti-aging techniques, uploading, even time travel.
If it's worth saying but not worth its own thread even in discussion it goes here.
