Death counts don’t tell you much. If the main effect of the virus is ultimately to advance a bunch of older people’s deaths by a year or two, then it’s not a big deal. People live and people die, that’s life.

"Deaths among adults 65 and older accounted for 80% of excess YLL in April but only 36% of excess YLL in June. Since April, working age adults 20-64 have accounted for 47% of excess YLL, and males 20 to 64 have contributed 34%."

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.

Stipulation: if the baseline life-length is 80 years and a ninety year old dies, then the YLL is 0 and not -10.
No, of course it isn't.
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.
