Mixed Feelings: The Complex Reality of Increased Life Expectancy in the U.S.
The increase in life expectancy in the U.S. is not a cause for celebration, as it is primarily due to the "healthy survivor effect" caused by COVID-19. The pandemic has disproportionately affected individuals with higher risks, resulting in a survivor cohort with longer life expectancies. However, COVID-19 is still killing a significant number of people, preventing life expectancy from returning to normal or reaching all-time highs. If the virus were eliminated, there could be a dramatic increase in life expectancy, highlighting the impact of pathogens on aging populations.
