Article: Exercise is an important part of losing weight, burning calories, and maintaining health. Moderate exercise means that you are lightly sweating, breathing a bit harder (but are not out of breath), and can still talk while exercising. Moderate aerobic activity may include dancing, cycling, and brisk walking. Vigorous cardiovascular training burns calories faster, and includes jogging, circuit training, aerobic classes, resistance training, and stair climbing. One way to engage in fitness in a new way is to try a new activity.  This can be as easy as trying a new class at your local gym or trying something active outdoors. You want to make fitness fun, and there are many ways to add enjoyment to physical activity.  Hiking is a great way to burn calories and be active while enjoying some natural beauty. If you don't have hiking trails near you, consider going to a local park or somewhere you can immerse yourself in nature while you move your body. Pick up biking. Find some local bike paths and enjoy time outside. Save gas and bike to your errands, like going to the grocery store. Dancing is a great way to burn calories and learn a new skill. Many different forms of dance exist, such as ballroom, salsa, bachata, hip hop, ballet and freestyle. Check out dance classes in your area and have some fun while you burn calories.

Good dental hygiene can kill the bacteria that might cause aspiration pneumonia. Use a soft-bristled brush to clean the outer and inner surfaces of the teeth. If you use dentures, remove them before brushing. If you’re assisting someone else, stand behind them and off to 1 side. Wear gloves. Peel back their lips with your fingers before brushing the teeth and gums thoroughly. A good mouthwash will kill bacteria in your mouth, even if you don't have teeth. Swish or gargle the mouthwash for 30 seconds before spitting it out in a sink or cup. If desired, add cleaning tablets to the water. When you remove the dentures in the morning, rinse them off with clean water and brush them before putting them in your mouth. Flossing helps remove bacteria between your teeth. Use about 18 inches (46 cm) of floss, and wind the ends around your forefinger and thumb. Slide the floss up between your teeth and down again. If you’re assisting someone else, make sure to wear gloves.  Don’t snap the floss between the teeth. Instead, slowly ease it up and down. If you’re helping another person, standing behind them may help you floss more easily. The dentist can clean your teeth to protect you against bacteria that can cause aspiration pneumonia. They may also do screenings to evaluate your risk of aspiration or your ability to swallow. If you’re a nurse or caretaker, arrange regular dentist visits. If the person is unable to leave their bed or home, see if you can find a dentist who will perform an oral screening at your home.
