Despite all of the things that you could be doing, it's easy to get into a rut when you're retired -- especially if you live alone. Sitting around the house isn't just bad for your mental health, it's bad for your physical health as well. It's OK if you have limitations -- even if you have problems with your mobility, there are exercises that you can do to keep yourself fit. Check out your local library for books and DVDs with exercises geared toward seniors or see what local gyms have to offer. Some gyms have discounts for senior citizen memberships, and they also have fitness instructors who are trained to work with seniors. Some shopping malls have walking clubs that meet on a regular basis to get exercise in a climate-controlled, level environment.
Being active doesn't just mean exercising, though. If you're the only person who has retired in your circle of friends, you may find that you don't have as much in common with them. Often, retirees in cold climates move to warmer parts of the country, so even your retired friends could disappear. You may have to seek out new friends, and the community senior center is a place to start. In addition to classes, senior centers offer recreational and social opportunities. They often hold luncheons and dances and organize day trips to places like historical sites and shopping destinations. Senior centers also may have clubs or groups for different interests, such as book clubs.
