> Researchers from the university separated respondents into three groups, based on age. One group was younger people, between the ages of 18 and 29, another group of senior citizens whose average age was 72, and a third group made up of individuals whose average age was 88.
18 - 29: 34% Yes, 40% No, 26% unsure
Average age 72: 32% Yes, 43% No, 25% unsure
Average age 88: 24% Yes, 59% No, 17% unsure
> Differences in responses emerged along gender lines as well, with more men saying they would take the pill than women.
And ironically:
> "If a life extension treatment were to become available that effectively stopped ageing, young adults may be likely to use such a treatment to avoid reaching the ages at which older cohorts say they would prefer to live forever," the study determined.
And then avoid social media, clickbait, ragebait, idling, gossipping, and live in a deliberate and conscious way to make the best use of their time (best according to their own metrics).
(Given that 66% of people are overweight, seeing 59% say they would like immortality suggests there's overlap. Not that I'm preaching, I don't do much of that stuff, and there is argument to want immortality to fritter away on enjoyments and relaxing and that maybe people are unhealthy because they are 'driving it like they stole it' for their limited time - but it's possible to play the finite lifetime cards we're dealt a lot better than than most of us do, without even getting to extremes and maximising things).
Y'know, given that "multiplying it indefinitely" is not actually an available option, whereas not dying at 72 from lung problems from a lifetime of smoking after several years of being nearly housebound then almost chairbound is an available option.
