I was just discussing this with my oldest son the other day.
The world is not safe (especially in big cities) to allow a younger child to ride their bike, skates, etc to the park
without an adult with them. Some can't even play on the streets.
They pretty much have to get their children involved in activities they have to pay for after school to get healthy exercise.
You can't send them to the store alone as I was able to do.
I have given prayers of gratitude thousands of time for the nudge to leave L.A. back in 1979 and get my kids to the
country where they could roam, explore and neighbors knew them.
I will stop on that note so others can name all the other reasons, as there are many. I am so thankful I was able to
see my boys come in for dinner totally wiped out and safe and not in trouble and were proud to share their exciting
finds and discoveries of the day.
Exploring outdoors where they learn cause/effect, prediction, more/less. life circles, nature signs develops common
sense. So I don't have to wonder why so many young ones really don't show signs of this much needed intelligence.
