You're perfectly entitled to feel that way. There's no objective set of human incentives/desires and everybody is entitled to his/her own utility function. For me, I'm too curious about what the future will bring to die now or any time sooner than is necessary. Learning, satisfying my curiosity, and gaining new experiences have thus far provided me uncapped positive utility and I expect to continue to feel that way into the indefinite future. If I didn't have that love for science and technology, I could expect that long life would become monotonous. The only opinion I won't abide is that of someone who not only doesn't want to live longer, but also doesn't think I should be allowed to.
