Hi Diana, have you seen Ricardo? No, I haven't seen him. Why? We have to organize a project, we're going to have a presentation for science class tomorrow. He sometimes arrives late to class, he said that he woke up late, because he spent a lot of hours on social media at night. I'm worried, I noticed that he was tired yesterday, he didn't pay attention to the class, he didn't do any homework. Ricardo told me that he played from five to six hours of video games every day. He should reduce the use of social media and video games, and interact more at school. Yes, some studies have found that spending an excessive amount of time on social media can cause feelings of sadness and frustration in people's lives. I understand some studies have found out about it. I used to spend a lot of time on social media too, I felt anxiety, and I couldn't sleep very well months ago, but I changed my habits, I share special moments with my family and friends, I exercise, and I haven't used my cell phone before going to bed. I totally I agree, good habits can make our lives longer.
