It is common knowledge that the health is general thing in life. If you are healthy you can do everything. You can do some sports to keep fit or do elementary things. Let's speculate about importance of health. 

Health really is essential. You need to eat healthy food, to workout and so on for a good health. You must give up bad habits. 

In my opinion, when you are healthy you feel good. Everything we do is based on our feeling. If you feel bad,  it can reflect your activity. But if you feel good, you have many abilities. Secondly, your relatives are glad and you are glad too! Isn't it great ?

To a certain extent, it is right, but we shouldn't forget that there are many people with different values in their lives. For some people the most important thing in live is career. They put it first. They do everything for a good job.
