Long For This World: The Strange Science of Immortality by Jonathan Weiner
My rating: 4 of 5 stars

Author’s book site

This book considers the science around the question: will there come a day when human beings live forever (or at least considerably longer than we’ve achieved to date? — i.e. hundreds or thousands of years.) A secondary question, explored in the last of the book’s three parts, is should we want to?

It was a courageous decision to write this book because it focuses heavily on the ideas of one particularly controversial figure, Aubrey de Grey. And by “controversial” I don’t mean to the general public, a public which has limited understanding of the science involved, but rather a man who is controversial to many (perhaps, most) of his peers. Of course, with a Pulitzer under one’s belt, one can afford to take a few chances. (Weiner won in 1997 for The Beak of the Finch, a popular science work on evolutionary biology.) To be fair, Weiner does not present Grey’s ideas from the perspective of an acolyte. On the contrary, he is clearly skeptical and not shy about presenting the countervailing arguments put out by others in the gerontological field.

I can see several reasons why Weiner chose to focus on Aubrey de Grey. First, De Grey is an eccentric figure, and that makes for more interesting reading. Second, De Grey also takes the boldest possible stance on the topic (i.e. that there is no reason humanity won’t be able to overcome aging and death, given sufficient time and effort.) Finally, De Grey has a readily digestible roadmap for eliminating aging. De Grey identifies seven problems that must be solved, arguing that the last — i.e. defeating cancer — is the only one that will present a true challenge in the long run.

While I wasn’t converted to a belief that immortality is inevitable (and that wasn’t the book’s objective, though it may be de Gray’s,) the book does offer interesting food-for-thought, both on the scientific question of what it would take and on the philosophical question of whether we should want to.

If you’re interested in aging and mortality, I’d recommend reading this book.
