Retirement Activities
It is just as important to keep your brain active as it is to keep your body in good shape. Many studies have shown that the brain needs challenges at any age. It is very easy to get depressed and/or to think that retirement means that you don't have to think anymore, but that is the worst thing you can do.
Retirement should not be putting your feet up and sipping a drink. Sure you can do that too, but you need to get active physically and mentally as well.
The great thing is that you can have fun doing this. Lots of puzzles, games and hobbies are out there to challenge us. It takes an effort to get going, but you must try to get yourself in the right frame of mind to take up a hobby or do daily puzzles and/or games.
Try lots of different things until you find the one or two that give you the most pleasure. If puzzles and games don't work for you, try learning a new avocation, by taking courses to learn about jobs and experiences you never did when working. You may find a part-time job doing something you like. Volunteering is also an important option.
Most colleges and universities offer courses to seniors on just about any subject, and often they are free or very inexpensive. Try studying history or philosophy or things that you would never have thought about when you were working. Contact your local university or college to get more information on senior's programs and education.
Try the arts such as acting, painting, sculpture, carving, etc. Often people discover that they had a hidden talent that comes to light on retiring. Many people have become famous after they retire, maybe that is you!
