If you spend time at a theme park you know it can be a lot of walking. In some cases it’s 5-10 miles in a day complete with stairs and hills at some parks. That can be a serious workout and a new article in the Canadian Medical Association Journal found that it could actually be incredibly good for your health. The study showed that older adults who got 150 minutes of aerobic activity every week lessened their mortality risk by 31% compared to those who do not exercise. This means that the weekend trip to your local park with your season pass is “healthcare” if it gets you off the couch and away from screens.
