As @gu_h-àrd_gruber_an_cult has pointed out, it's not quite how the averaging works, but at the same time: that's not as unreasonable as you make it sound. Swedish overall life expectancy is 'just' about 82 years, true. But that's at birth. If you are already 82, the expected number of years to your death hasn't dropped to 0.
