Recent Sloan Fellow on Aging and Work Leah Abrams, PhD, is lead author on A Brief Report published in PNAS Demography that explores what could be driving the troubling status of U.S. life expectancy which has been stagnating since 2010. Abrams and her colleagues find chronic disease at the time of retirement to be a bigger factor than the ‘deaths of despair’ (drug overdose, alcohol abuse, and suicide) that have been impacting many mid-life, working-age Americans.
