Women aged 65 will now live for a further 24.1 years, down from 25.1 years in 2013. (Same reported also cited here http://www.independent.co.uk/news/uk/home-news/pensioners-uk-life-expectancy-falling-institute-and-faculty-of-actuaries-a7661571.html http://www.independent.co.uk/news/uk/home-news/pensioners-uk... ) The analysis seems to focus on first order changes, not longer term second order changes so if there was an effect like you describe e.g. those born 80 years ago being much healthier than those born 60 years ago, their positive contribution might mask deeper problems. The UK's ONA publishes various mortality related data sets here - https://www.ons.gov.uk/peoplepopulationandcommunity/birthsdeathsandmarriages/deaths https://www.ons.gov.uk/peoplepopulationandcommunity/birthsde... - might be an interesting side project for someone with time to spare...
