Darlene Howard, age 72, sometimes uses podcasts to help her keep up her walking routine. A former principal investigator at the Cognitive Aging Lab at Georgetown University, Howard knows from her research that exercising is the best way to maintain cognitive health as she ages. But “walking can get pretty boring,” Howard says, so she uses her exercise time for podcast listening. “This makes me look forward to the walk and often to extend it, so I can finish a particularly interesting piece.” Podcasts can help you keep up with current events and learn new things, even with the sensory losses that sometimes accompany aging, Howard says. “You can listen to podcasts even if you have vision problems, and you can play them at the volume that is best for you if you use earphones,” she says. “You don’t need to hold a book for an extended period in order to enjoy them, a boon if you are suffering from painful arthritis.” Advertisement Many podcasts comprise episodes that are part of a series. You can listen to a single episode, or sign up to subscribe to a particular podcast to get new episodes sent to your device automatically and typically free. There are a lot of ways to access podcasts. You can download podcasts and podcast apps from Apple’s App Store or Google Play for Android-based devices.
