Sadly American life expectancy fell again in 2021 because of Covid and drug overdoses according to the CDC. The Hill

Life expectancy was supposed to continue rising due to advances in medical technology that allowed more people to live long past what previous generations did. Unfortunately, Covid 19 and narcotics got in the way of the upward trajectory and continued weighing down the up arrow on the graph of average life duration. Hopefully 2022 will prove to be a year when the average life expectancy begins to point start going up again but that will depend on a variety of factors and it may not be easy to right the ship in just 1 year.
