If I could guess, 100% of the people are male. Polyamory is usually one guy and more women and is usually quite the sexist thing. Seeking life extension is at the current point of science not really rational.
Thank you for making a testable prediction. Your hypothesis is thereby falsified.
"Polyamory is usually one guy and more women and is usually quite the sexist thing. "
Good heavens, what sort of culture-free hole were you raised in? Do you know anyone polyamorous in real life?
"Seeking life extension is at the current point of science not really rational."
And there you have it. If you're anti-fun, you're probably also anti-life.
Not seeking life extension at all is definitely not rational. Perhaps it's rational not to seek it personally, but that's a personal choice. I think our society should seek life extension as an ethical choice.
