It's not like the life extensions pills would make you impenetrable to bullets. Or just stop taking them if you stop liking it. Anyways, if the most important thing to you is visiting a new restaurant every day, perhaps immortality really isn't for you - doesn't mean there aren't people who would make much more of the gift, e.g. see another star (or a dozen) or something, hmm, more imaginative.
I think the motivation is not so much the living forever but being scared of dying. If you have children they can enjoy the future. That's how it works.
Dying involves"dust to dust, ashes to ashes". Everything we have pumped ourselves up to be is gone. That is the fear. Spend the money on teaching people death in old age is OK.
