This got adjusted in the patch notes, and I feel that it is over represented in game. People tend to get very care intensive in the final few years of their life, regardless of how long that life was. People who’ve lived healthy lives and are going to live well into their 80s tend to be quite healthy in their 70s. Conversely people who have lived a lifestyle that will kill them before 60 get to be health care intensive in their 50s.
Therefore I would argue that if anything life expectancy would have little impact on health care demand.
