The document warns that excessive time spent on the internet can negatively impact health and social life. Too much computer use is linked to obesity, back problems, and vision issues from sitting still for long periods. Violent games may increase aggressive behavior, and spending hours online can cause people to skip meals and neglect real-world relationships and hobbies in favor of social media and information gathering. Saying things anonymously online that one wouldn't in person can promote cowardice, depression, and anti-social tendencies.
