In my home state, the average age of death from COVID-19 is 82. Average age of death in the state is 80. And the vast majorty who died from COVID-19 had other health issues.
If a disease kills people at an average age of, whatever 40, the average 40 year old has another 45 years or whatever, so that's 45 years lost. I don't want to seem uncaring, but are there any calculations on the number of potential years lost, rather than lives lost?
