according to the place people were born in. Take people who live in Africa,for example.
In fact, they are deeply impressed by their countries. This is why some of the are black
and look srict. On the contrary, if study the people living in Europe, you may find lots
who are calm due to the fact that they live in cold
places.

Moreover, people are impressed by the food they
eat. Those who are vegetarians differ from those who like eating meat. Therefore, their
mood and nature are highly impressed by their meals. Some beleive that vegetarians are
simpler and kinder.

his mood and nature. Dealing with people who work in mines is totally different from
dealing with people working in hospitals or airports. This means that it is important to
choose the right job because it affects your personality and the way you
behave.
