Malcolm Sears, professor of medicine, is featured in a 2016 documentary series chronicling a study of the lives of 1,037 people born in Dunedin, New Zealand during 1972-73.
Sears was an original investigator of the Dunedin Multidisciplinary Health and Development Study, a long-running birth cohort study that has followed nearly every aspect of the participants' health and development for over four decades. The documentary series, Predict My Future: The Science of Us, reveals some of the impactful findings from the landmark study.
Episode 4: Dirt is Good, Dirt Poor is Bad features interviews with Sears and reveals how excessive cleanliness affects asthma and allergies; how poverty gets under the skin to cause lifelong damage; the physical effects of social isolation; and how mental illness and Alzheimer's can be predicted by looking at the back of an eye.
Episode 4 can be viewed on TVO until Feb. 22. The full series is also available for viewing on the website of Australian national public broadcaster SBS.
