both wanted to prolong their lives. I don't think anyone would characterize the emperor of china nor steve jobs as 'procrasturbators'.
You make it sound like active people ( who don't waste their time ) feel that life is long when it's precisely the opposite. It's those who don't waste their time who want to live longer because they have so much more to do.
Then again, 'wasting time' is a concern for many precisely because life is short.
