Interview with Jean-Claude Henrard, professor emeritus at the University of Versailles – Saint-Quentin-en-Yvelines and gerontologist. Professor Jean-Claude Henrard advocates a multidisciplinary approach to aging. He criticizes the view of old age that reduces it to a purely medical concept and emphasizes that older adults must have a place in society. To improve the quality of life for older adults, we must address the social determinants of inequality, which have an impact throughout the lifespan.
