Life expectancy at birth rose for most of the last century as infant deaths and infectious disease fell. It dipped during the 1918 flu, again with the opioid crisis, and sharply in 2020–2021 with COVID-19, then began recovering.
Birth-year figures: CDC/NCHS life expectancy at birth (data.cdc.gov w9j2-ggv5, 1900-2018; NVSR/Data Briefs 2019-2023). Current remaining years: SSA 2023 period life table. Averages, not predictions.

Why is my life expectancy now higher than it was at birth?
Life expectancy at birth includes everyone who died young. Once you have survived to your current age, those risks are behind you, so the average age you can expect to reach goes up. Medical and public-health gains since your birth also help.
