I think NO. Because reading makes us more creative, and Creative people can generate several different ideas. People who like to read books are more creative and their reading habit broadens their thinking circle. It also improves sleep if you are regularly going to read before bedtime, then soon the body will get used to it, and then reading becomes a kind of signal. It improves the brain activity; in reading we usually think of a lot of detail: the characters, their clothes and surroundings. You must also remember the many things that are needed for understanding the work. That's why reading improves memory and logic. We are able to memorize more and more names of different places things etc. Books reading also improves concentration, when reading is necessary to concentrate on the content of the objects, without being distracted by other objects. This skill is very useful for any other activity

I believe that NO. I think people who often swear are not honest. I take the view that they get used to swear from childhood, because of nobody believe to them, so it is like their habit always to swear and try to proove you that "now" they tell the truth.
