I personally do not find the idea of endless life in this world appealing at all. I don't even get the desire to live to 100+, nevermind 200. I tend to think that the 'longevity desire' is prompted within oneself when one is not living according to whatever-it-is one thinks one should really do. The rat race is compelling sure, one needs money etc, but that is not the entire purpose of life. Perhaps some seeking/introspection is needed to make life meaningful.

Happy people are generally OK with going anytime, grateful for every moment and experience and only want to have closest ones taken care of. Unhappy ones, especially when its something deep and hard or impossible to tackle, want more and more, like they could somehow fix things in future or cover them up enough to finally arrive at that point they'll never arrive anyway.

Project it to some extremes and its easy to see why sociopathic dictators and billionaires (which most if not all of them are) would love to see significant life prolongation, of course only theirs. One of the biggest threats to near future mankind as it is IMHO, imagine 300 years of rule of pos like puttin' for example.
