I guess you are right mate. Many studies have shown that human beings reacts differently depending on the situation and the environment. Thus small cities are less active... Drug consumption as well is higher in small cities as people have less hobbies and activities.
That shows a pretty sad picture. People from the city do not know to live in the nature. And people from small cities to show success or even just to evolve have to move to bigger cities... More opportunities, more interaction. So less time to focus on themselves and simple things of life. What do you think about it ?
