The social media are a big new world in the contemporary society. For the people who had grown with this smart tecnology since childhood isn´t to hard to understand, but for the group of people how used to do everything at the "old way" is a real challenge. In my case, I fell more like a person from the first group. The first time that I'm log in on a social media platform was in 2008 and since then I'm in love of Facebook. At that time, my parents told me: "Martin, don't put your personal information on websites, this is pretty insecure", and... it is! If you ask me about the limits that everyone must to have for a safety "virtual live", I would tell that you don't depends of any social media, your life is outside of the screen.
