Coming to the health of people in regard with pollution. Since cities are heavily populated and each member having vehicles, the amount of pollution is extremely high in cities and this has led to great amount of pollution and allergic diseases, even in small kids.
However, in villages the question of pollution does not come up to that level of what it is there in cities and hence fresher and less polluted air is available, which is good for both health and mind. People are more systematic and scheduled and get their work done by themselves rather than calling up or outsourcing the day to day household chores.
