Screen Time. Years ago in 1990, the average time kids spent on screens was 3 hours a day. That was time mostly spent watching TV. I was a teenager at that time. Currently screen time is up to 6-8 hours a day for the average teenager. This is astounding how much time kids spend on screens. They are missing out on so much living. The book goes on to say that 112 hours a week is the amount of time that kids are not actively not present. This is extremely alarming. Again, kids are not learning real life skills and social skills they need to be decent functioning human beings.
