Do you want to live to 100? Thankfully we have a better chance today because U.S. life expectancy has risen considerably, from 59.6 years for those born in 1922 to 77.5 years for those born in 2022. (Several websites will estimate your life expectancy including Northwestern Mutual’s Lifespan Calculator, media.nmfn.com/tnetwork/lifespan/index.html#0, which I’m sure is the most accurate because it determined I would live to 96!)
