   Health and fitness are not just for young people. They are for anyone willing to accept the rules of a good diet and regular exercise. With age, there is a tendency to feel that the body is no longer able to perform well. Yet example after example shows us that older people can – and should – be active. Many men and women in their sixties have run in marathons, races of more than sixty – six miles.

   For most people, they need simple activities like walking and swimming to stay in shape. It’s important to include exercise in your daily routine. In the winter, do push- ups, sit – ups, and other indoor exercise.

Who are health and fitness for?

Living in the country is something that people from the city often dream about. However, in reality, it has both its advantages and disadvantages.
There are certainly many advantages to living in the country. First of all, you can enjoy peace and quiet. Moreover, people tend to be friendlier and more open. A further advantage is that there is less traffic, so it is safer for young children.
However, there are certain drawbacks to life outside the city. Firstly , because there are fewer people, you are likely to have fewer friends. In addition, entertainment is difficult to find, particularly in the evening. Furthermore, the fact that there are fewer shops and services means that it is harder to find work. As a result , you may have to travel a long way to work, which can be extremely expensive.
In conclusion, it can be seen that the country is more suitable for some people than others.On the whole , it is often the best place for those who are retired or who have young children. In contrast , young, single people who have a career are better provided for in the city.
