"Work expands so as to fill the time available for its completion". Perhaps we'll find the same is true about life itself. We'll live twice as long, but we'll be twice as cautious, twice as likely to say 'tomorrow'.
Everything has to end. Even the human race. For me the deadline gives our activities meaning. Ironically, even your eager desire to extend longevity only has a sense of urgency and interest because we die. But the actual lifespan itself will always be arbitrary, a number picked out of a hat. So why isn't 80 years ok? Why is 160 years really better?
In fact, wouldn't faster generations make the world even a bit more interesting?
I may still be too young at 25, but I can't think of a single time in my life where the threat of eventual death was a motivator of any kind. maybe as I get older it'll come, but only because it'll be just over the horizon. If I lived 800 years instead of 80, it might motivate me for the last 30 years, but that still gives me an extra 690 years of being motivated by other factors (happiness, comfort, pride, love, whatever floats your boat).
