People spending 2 hours per day to use social networks can be separate.

We and other people use a social network every day. We check Facebook to see what our friends have posted, or move to Instagram for looking what they have eaten in the afternoon.

However, a new study shows the more time young people spend to use social network the more highly they can be separated from social. According to a new article posted in American Journal of Preventative Medicine, people signing up in social networks two hours per day can be separated from social twice as much as the other people using them just 30 minutes every day.
