Are poles generally healthy ? Justify your opinion

Are poles generally healthy ? Justify your opinion. (dział 11, str 59 Repetytorium - Misztal, Mrozowska, Sikorzyńska))

In my opinion Poles are generally healthy. I think that we can divide people into two groups.
In the first group there would be people who are young, fit and healthy. They like sport and doing some exercises. They know that it is very important for their health and body. But I think that having a lot of free time and willingness is also important. The second group would be the overweight people who are workaholics and do not have enough time to do exercises. When they came back from work they want to lie on the sofa and watch TV or read a book. They are tired and just do not want to do some exercises. It is sad but true.
Another important thing is good and healthy food. A lot of people who work very hard and long do not have time to eat healthy food and take-away meal or fast food. But I think that nowadays much more people prefer to eat some salads or fruit to stay in a shape. They realise that eating a lot of unhealthy food may bring terrible effects.
In my opinion stress also destroys our bodies and minds. If we want to live long and healthy we have to cut down on it. We have to eat more healthy food, do a lot of exercises and minimise stress in our life. Otherwise we will never be healthy.
