Well, screen time I imagine would also not induce diabetes or clogged arteries in children 9-12. but it will few decades down the line if they don't ingrain good habits because of that screen time. Same with this, if MRI does not detect brain "hardware" damage, that does not mean there are no software damage done to kids with excessive screen time at young age. I had a son 2 months ago. One of my biggest concerns is how to protect him from excessive screen time and social networks until he grows up enough (~14 years at least). I plan to do a lot of nature going (with some backyard astronomy and biology if that piques his interest) and sports, active travel.. We'll see how it goes
