My 5th grade teacher (a sort of benign philosopher) once related to me that when he was young he strove to take advice, and that meant spending time thinking about the beauty of youth, as his mentors urged him. He seemed to realize how much better it was to be young, and that he could not, would not bear old age. He explained to me that he and his friends would all commit suicide once they turned 40. Since he was in his 50's at the time, I asked, "What changed?" He replied, "I turned 40."

You have an extremely negative outlook on improving life expectancy ("So what?"? Really? Does life not matter at all to you?) in absence of pure immortality (a distinction I'm not even sure we'd be able to make in the ideal case), in such a way that I think any normal person would safely call bullshit on those being your preferences when it matters.
