SENS isn't about death. It's about undoing aging. For as long as I am alive, I'd rather stay as young and healthy as possible. Wouldn't you?
Youth isn't just a question of fitness and years. Youth pulls in recklessness, a belief in your own immortality, an uncertainty about who you are or what you're for, and a diminished awareness of the past (because you've experienced less of it). There's no medical treatment or fitness regime that will give those things back to you.
If you even want them; the loss of those things, or at least some of them, might be considered wisdom.
