Me, three years ago:
The current drops in life expectancy are due to two historical blips: the opioid crisis, which killed fewer, but they were younger so they might lose decades of their life, and Covid, which killed more, but usually folks either older or infirm, taking maybe two years of life from them on average.
Expect stories about surprising jumps in life expectancy over the next few years.
