"A large analysis found that the majority of these deaths were not just among the extremely frail, but in people who likely would not have died within the next six months, and that in most cases, life was shortened by at least one year. Some cases will have less time lost, but it is rare for heat death to simply advance death by only days or weeks.

In quantitative terms, heat deaths tend to "cost" between six months and a few years of life per death on average."

You gotta die of something.
