The Limits of Aging & Implications

Originally broadcast November 6, 2024

The current life expectancy at birth is 74.8 years for males and for females it’s 80.2 years in the U.S. Does it catch your eye when you hear about predictions we’ll be able to live to 100 and beyond? Some researchers are throwing cold water on those notions. “We’ll be lucky if 5% of the age cohort makes it to 100,” says S. Jay Olshansky, Ph.D., Professor, University of Illinois at Chicago.

He and his colleagues made headlines when they presented data that humans are approaching a biologically-based limit to life. Hosts Mark Masselli and Margaret Flinter ask Olshansky about the implications of this research — for each of us personally and for policymakers — after decades of hearing predictions that life expectancy would continue to go up. Olshanky explains why we should celebrate longer life that has resulted from healthier diets and medical advances but now focus on improving quality of life in later years.
