Maybe, but the percent of US population that is 80+ has grown quite a bit. For example, between 1950 and 2020 the percent of those 80-84 more than doubled. In the same period those 85+ went up five-fold (source: https://www.urban.org/sites/default/files/2015/10/09/t2_age_...). IMO this is the result of modern medicine extending lives well beyond where they would have gone before. Based on my parent’s experience, once you’re kept alive by machines and medicine, your quality of life sucks.
