As a retired family doctor, 76-year-old Norm Schroeder knows a thing or two about how to live a healthy life. That’s why, for the last eight years, he’s been keeping his mind and body active by taking classes through the University of Wisconsin-Green Bay’s Lifelong Learning Institute. And he’s been encouraging others his age to do the same. “(It’s) good for our brain health because there’s cognitive stimulation in the classes where you either can learn new things, or relearn things that you’ve forgotten many years ago,” Schroeder told WPR’s “Wisconsin Today.” “And for our physical health, we even have classes in line dancing, nature hikes and bicycling. I can cover all those bases.”
