Vassar's second post makes me see another good reason to focus on cryonics vs. other luxury goods. Even if cryonics has a higher expected return, it's so deferred, abstract, and uncertain that the willpower cost of not purchasing cryonics is very low compared to other luxuries.
BTW, the first comment on that article is depressing: "I feel sorry for society in the future!"
...on signing up for cryopreservation with the Cryonics Institute.
(No, it's not a joke.)
Anyone not signed up for cryonics has now lost the right to make fun of Paris Hilton,
because no matter what else she does wrong, and what else you do right,
all of it together can't outweigh the life consequences of that one little decision.
Congratulations, Paris. I look forward to meeting you someday.
Addendum: On Nov 28 '07, Paris Hilton denied being signed up for cryonics. Oh well.
