Expectations of future UK life expectancy have declined for several years now. This is not to say that current life expectancy has decreased, but rather than estimates of future mortality improvements are being lowered, pushing down future estimated life expectancy.
One report indicates this change may roll back a year of expected mortality improvements. So perhaps those optimistic stories about “the first person to live to
200 1,000 has already been born” will fade for a while.
The thing is, it’s no utterly crazy to think about extreme life extension for currently living people. We don’t need to solve ageing in the next 40 years for a 40 year old to live to 200 or 1,000. In the next 40 years, we need to extend life by enough time to allow the research for the next 40 year extension and so on.
I’m feeling a little old myself with a milestone birthday coming up in a couple of days. For now, 50 years still feels like a long time, although Asimov’s The Foundation series and the Long Now crowd would likely shame me into thinking I am a super myopic actuary.
