<Snipped quote by Techspert>

I feel like most people would live longer with immortality, other survival factors included or not. Most people don’t just keel over randomly, or throw themselves into danger on a whim.

The longer you live, the more you get desensitized to danger. You start to think "Wow, I've survived so much. It's almost like I'm immortal or something." And then you remember and go "Oh wait."
