 So this is like what grandma would have said, get outside and play for one hour. And I mean, it's pretty easy. Kids without the influence of screens, that's easy for them to play for one hour a day. That's not a big deal. So one hour, get outside or inside, but physical exercise, sleep for eight hours a day and limit your screen time to two hours or less. And if you can get there, your kids will be set up to be much healthier than the average child.
