The Aletta Jacobs School of Public Health is organizing a summer school on health equity from July 1 to 5. Growing older leads to more health problems, that's natural, but even within the same age groups, health is not equal. According to Marije Bosch and Erik Buskens, the coordinators of the summer school, that's a big problem. ''We need to create an environment where people are empowered to engage in healthy behaviors, thus preventing unwanted and unfair inequality.''
