University of Pennsylvania geriatrician Anne Cappola, a member of the National Academy of Medicine, said in an interview with Microsoft and MSNBC. Cappola said in an interview with Microsoft – National Broadcasting Network (MSNBC) that the secret to staying healthy in older adults is exercise, and a lack of exercise can cause a host of problems. “People try strength training like resistance training and try to walk more to exercise, but it’s harder for older people who have a limited range of motion,” she said, adding that older people can try to walk faster, which is also good for their health to some extent. The World Cancer Research Fund in the United Kingdom said brisk walking can speed up the heart rate and promote breathing, which is one of the “moderate physical activity” ways to prevent cancer. The foundation launched the “Walk Together” campaign last year, calling on participants to walk with their families and friends to encourage them to develop habits that help reduce the risk of cancer. The World Cancer Research Fund said that despite evidence that physical activity helps prevent cancer, “only about a third of the population is aware of it, and there is still a lot of work to be done to raise awareness”.
