The average 8- to 18-year-old spends D. 3 hours or more per day on average in front of a screen doing very little to no physical activity. This is because children and teens often chat a lot, or watch a lot of movies/shows, or play video games on their computers instead of exercising and going out with their friends. This is often much more than three hours a day, unfortunately. Although there are some kids who still prefer physical activities to this, it still applies to the majority of population.
