Get moving! Four in five adolescents don't exercise enough: WHO

Being obese and physically inactive doesn't seem to have stopped a certain 73 yr old American male. Yet.

I reckon Japan will score very highly here. My own children and those around them do an hour a day pretty much just walking or cycling to school. They then have P.E. classes three times a week and do clubs on the top. What they don't do is unstructured stuff with friends like I used to, but I think that is a thing of the past. Unless you actively stop them, many gatherings of kids now descend into them huddling around a screen.

Japanese kids move a lot in my area. Even the chubby ones are out there doing things.

The human physical and mental constitution is much like a building - in the early stages of construction flawed foundations lead to problems later on. The twenty percent of kiddos will have a great advantage eventually in their lives.

146 Countries and territories were part of the study, but for some reason (surprising to me), Japan was not included. I wonder why.

The keitai zombie in Japan is always able to shuffle around, but may be a danger to the living...
