Oh, you live in friggin' Rio de Janeiro? Must be neat to have a world wonder on your back porch. But I've heard some pretty bad stuff around there. Like crime is pretty bad in some areas of the city.
Yea, it's cool to have a wonder nearby. The view can be quite inspiring. Regarding crime, yes it can be bad on certain parts of the city that you'll never go to, because you are not insane or drug addicted. For most of the places of the city, specially the touristic ones, it's pretty much bearable. It may happen things once in a while, but you really need some bad luck to something happen to you.
