The idea behind Drew Magary’s great new book is simple: aging, as it turns out, is caused by one gene. Shut that gene off and you stop aging; accidents and disease are still a problem, but you’ve cured death by natural causes.

Now compound that discovery with the fact that any person who gets the Cure simply stops aging. People don’t become younger, they just don’t get older, frozen at their “Cure age.” What happens next?

In an effort to find out, Magary takes us through the life of John Farrell, a New York lawyer who gets the Cure for aging at the age of 29 in the year 2019. From that point on, things go rather poorly for John and the rest of humanity. As one might expect, curing aging doesn’t cure social ills, over-population, ennui, or a host of other human hangups. Mark Frauenfelder has an excellent synopsis of the book over at boingboing.net, and I share his opinions about the book’s bleak tone and high quality.

Magary’s argument through the text is essentially this: death creates meaning. Not mortality, but guaranteed natural death due to aging. The idea that no matter what you do, how you live your life, the concept that you will be born, mature, grow old, and die creates human meaning. Magary has a point: from the riddle of the Sphinx to Tyler Durden to the final books of Harry Potter, aging and death seem to be at the epicenter of human thought. I don’t deny him that at any moment any one of us could meet a tragic end. Life is precious in part because it is not meant to last.

But here is where I struggle. The Postmortal is not about a post-mortal society, it is about a post-aging society.

Lots and lots and lots of people die in Magary’s vision. In fact, he seems to argue that in the absence of death, people will not only seek death but will create circumstances that create death and thereby, create meaning. It is only when Farrell’s life is most in peril that he finds purpose in existence.

But Farrell is never immortal, no one is. So my question is: is the process of aging as meaningful as the condition of being mortal?
