Therefore, you are a happy retired, living in a big house to take care of their grandchildren. What more could you ask for? Excuse me. In fact, there are many things you could ask for. Age is not a barrier to new hobbies.
When you're over 65 you have enough time to engage in activities that were previously inaccessible. Not enough time, money or energy just when you were young, now it's time to take care of you. There are so many opportunities for older people can not even imagine.
Start with the sport. Your doctor forbids you to play all sorts of sports like golf and chess? It is never too late to learn to play a new sport or improve your skills in your favorites. If you're in good shape, you might be interested in basketball, football, tennis and martial arts. But if your giggles are dusty, consider the less active games such as table tennis, golf, swimming, cycling, etc.. Do not be lazy, anyway is in your hands. Fitness is very important for the elderly.
Optionally, you can start to play mind games. Chess, poker and table games are an ideal way for your brain to exercise. Most of these games are family, there is another opportunity to meet regularly and family fun.
Let your feet do the walking. Walk every day in a park is a great way to stay healthy and fit. Morning or evening walks are very useful for the form and feeling. Also ideal for combining with other activities such as photography and treasure hunting (participation in different quest games).
Another great idea is why do not you take a class? There are free classes that will teach you many interesting things about the architecture, cuisine, crafts, sculpture, art, role-playing and so on. I bet everyone can find a class you like. Just visit some cooking classes and surprise your children and grandchildren with the chef's specialty. Or visit some acting skills classes and read a book grandchildren. Sources of improvement are endless.
We always take the time to travel when you're young, so it's time to think about that when you have more than 65 years. Imagine that you can leave any country, for any period of time, you do not have to return to work, take their children to school. Just you and a wonderful culture of another country. Older people are often very wealthy travelers, as they are able to find hundreds of hidden treasures that are often overlooked by other busy travelers.
Do you like fishing? Male retirement often enjoy fishing because it allows them to leave the noisy city life. All the problems are gone, it's just you and nature.
The moral of this story is that life does not stop when the head is silver. It is time to devote sufficient time for himself.
