Note that we shouldn’t be considering total health-adjusted life expectancy (HALE), but rather the HALE of the average person saved—hence you probably want to half that as a typical rule of thumb (not fully accurate, since disease burden is higher for old people, even as the average person saved is probably younger than the midpoint given global age distributions; evens out to some extent, but not clear how much so)
