Maybe I am misreading this, but when they say “using the mortality rates for 2019”, I think they are assuming that there won’t be increases in life expectancy. Like, we’re currently observing that people born in the 1930s living ~80 years, and so we’ll assume that people born in eg. the 1980s will also live ~80 years. But that seems like a very bad assumption to me.
