Study examines aging ‘Happy Days’ cohort

They say money can’t buy love, but could it change the structure of your brain? When the going gets tough, do the tough live longer? And if an apple a day keeps the doctor away, what can hard apple cider do? For 45 years, the Wisconsin Longitudinal Study (WLS) has provided policy makers and social science researchers with an unparalleled look at how education, career and family affect adult life. Housed in the Center for Demography of Health and Aging at the University of Wisconsin-Madison, this groundbreaking study repeatedly surveys thousands of 1957 graduates from all of Wisconsin’s high schools about their interests and experiences, habits and health.
