A gerontology research group is a group of people who study aging. The group may include experts from different fields, like scientists, doctors, and social workers, who all work together to research how aging works and how best to help people as they get older. The group does research on things like how different medical treatments affect aging, what kind of lifestyle changes can help people maintain their health and happiness as they age, and how to create the best possible environment for older people. They use this research to come up with ideas for improving the lives of older people.
