What can happen to people if they move to a big city???

In almost all the countries some people are acostumed to live in small cities with a very calm and peacefull life, and sometimes they have to move for another city for any reason. So the question is: What can happen to them if they move from a small to a big city??? Probabily with most of them nothing is going to happen, they'll continues the same as before move. But there is a big possibility that many people change their habits, behaviours, view points and their costumes. For example I would like to mention some behaviours that might change with this displacement of cities:

- People might became more agressive, it means; no pacient in the traffic and with the other people.
- Some people may be more isolated, spending more time alone.
- People genarally becoming more stressed, scared and exited.

I 'd like to remenber that I'm not saying that everyone whom moved to a big city become like this. In some people you can't see any displacement, they continues the same, nothing changed. There is a movie that you can watch that shows all of this I'm talking about. The name of the movie is Falling Down. It is kind of old but very interesting to show what could be the pertubation of living in a big city. I remenber watching this movie the first time I was very scared, but after a while I understood that it could really happen with a sensible person in a caotic city. My advice to you is to watch this movie and think about learning about this topic a little more.
