Answer 1

Answer:

The youth of the world is often the most ready to adapt to and learn to use new technologies, and they are certainly at the forefront of social media of all types. They have more technological know-how than many of older generations as well. Social media, therefore, is certainly having a rather large impact on their daily lives for good and for bad.

Those who spend too much time on social sites, or who take the abuses of online bullies seriously on the sites could have some issues. For parents, even those of teenagers who are 16 and 17, it is important to watch to make sure that social media sites do not take over the lives of children. When used appropriately, it can be a very good thing.
