I wonder how the median life expectancy has been changing in the past few years. Using the mean certainly allows for some shock and awe, and certainly serves to scare people (considering how much it is skewed by things like infant mortality, drug epidemics, wars, and most anything else that involves people dying at drastically different ages than the otherwise usual range), but it's always seemed to me that the median would be a more useful number. Indeed, the median has generally been a good few years above the mean, at least in America, though I can't say I've found tracking the data down nearly as easy as with the mean (okay, I tried for like, 7 seconds...but it wasn't in the top few results). Never mind the mode, which is even higher than either.
It'd be nice to see data compiled showing the relation of mean, median, and mode, plotted over time, for life expectancy data. At the very least it'd likely help curb inflation, as people recognize that they're going to need a lot more retirement savings if they're suddenly saving for an extra decade than they were expecting using statistics improperly...

But I fully expect median to have dropped almost as much as mean in this case, since the pandemic affected the older adults more, hence it should have shifted/compressed the entire right side of the death frequency over age graph. Anyway, in terms of measuring overall society, mean is better than median for life expectancy, since it gives effectively more weight to earlier death. Median/mode would be more useful for individual.
