Want to increase your own healthspan? The genetic die may be cast, but it’s still possible to add healthful years with lifestyle changes. Two recently published studies, one on U.S. veterans and one on U.K. civilians, help quantify by how much. Each study monitored nearly 300,000 people over a decade, tracking their lifestyles and looking for payoffs to healthy habits. The takeaway: small changes can have big effects, and big changes can have huge ones.
