Question: Would we mandate a drug that would make us live forever?

In the midst of all the debates we are now having about whether to mandate the HPV vaccination for 9 and 10 year-old girls, a question occurred to me. The justification for mandating it, of course, is that it will save some lives. Here's my question:

And do me a favor, read Natalie Babbit's Tuck Everlasting before answering this question.
