Nowadays most of video game(s) and film(s) environments are often based on violence and aggression. Many games only offer an arena full of weapons, killings, kicking, and shooting; so I think parents should have to spend more time with their children and help them to choose better things to entertain themselves with, entertainments such as do exercising or reading a book.
Violent video games may be related to aggressive behavior. The Over-dependence on video games could foster social isolation, as they are often played alone. This kind of entertainment(s) affects the relationship between parents and their children and takes children away from the church.

I believe it would probably depend on where the job is located. Certainly knowing English might be helpful pretty much everywhere; however, if someone is looking for a job in a Spanish speaking country then they best know Spanish. It would be the same case if someone was looking for a job in Europe; If someone knew multiple european languages then they might have a better chance of getting hired.
