YLL is an interesting metric but deceptive. As the article says, about 80% of deaths have been in the 65 and above bracket.

- adolph 6y agoWouldn't YLL be a better measure between pandemics? Lets say pandemic A kills 100 humans at 25% of life consumed versus pandemic B that kills 200h at 75% of life consumed. If only lives are counted then B is 100% worse. But if the human-years are measured then pandemic A is 50% worse. Given a zero-sum trolley car dilemma, is plain lives or YLL a better measure of utility? For example, if a person dies at age 50, and life expectancy at age 50 is more 25 years, then the YLL is 25. In contrast, if a person dies at age 80 and life expectancy at 80 is 2 more years, then YLL is 2. https://healthcostinstitute.org/hcci-research/the-impact-of-covid-19-on-years-of-life-lost https://healthcostinstitute.org/hcci-research/the-impact-of-... Stipulation: if the baseline life-length is 80 years and a ninety year old dies, then the YLL is 0 and not -10.

A 90-year old isn't expected to instantly die. They have some remaining live expectancy, maybe two or three years, even if they have passed median live expectancy.
