Is there anyone who reads this that has a valid argument in dissent of gerontology? I'm curious, as I know several people (all religious) who take offense at things like this because it's "unnatural." I haven't heard any solid argument, yet, though.

EDIT: Also, I think it is unfair to label people like de Grey or Kurzweil as simply "afraid to die." They just see it as a necessity for reaching the boundaries of human exploratory possibilities. Although it is true that new minds produce new insights, it is undoubtedly also true that if a single person could live for two centuries instead of one in a healthy state of mind, he could probably do more research in his field than two separate people in those centuries, since he would have both the advantage of more overall knowledge and passing on that greater collective to his colleagues and students (who in turn will likely benefit more than from a 50-year-old professor that has had less experience in the field).
