Some other factors could be better nutrition and improved health care.
It would be interesting to see if this trend is also true in the 3rd world countries where nutrition and health care has not improved. I'm guessing they are not seeing the same trend.
My 3rd grade boy (who is 8 years old) is 70 pounds alrea ...[text shortened]... he rest of the boys in the class. Some of the boys are already over 100 pounds (in 3rd grade).
But.....when I look back on say...my parents class photos, they all look like grown adults in jr high as well. So I guess it's hard to say really.
