I hate to burst your bubble, but my son, can build things, rode his bike everywhere. Is not fat at all. When he was 5 or 6 went collecting money for chocolate bars for his soccer team. He was gone for 3 hrs. When it was 8pm I started to be concerned, but he came home with a boat load of money. Of course I sent the dog with him, who by the way was not on a leash. Dog is a border collie so lots of energy, but would not protect or attack a soul.
My neighborhood, the kids are outside, do slip and slide, and wander in the woods making tree houses.
I agree that the video games have contributed to fat kids. My son would stay for hours in front of a screen.
Oh and for the lady who complained about being low birth weight and short because her mom smoked. I am small about 5 feet. My mother was smaller 4'10". My brothers about 5'8". I am small because my genetics are small. My son is now 5'10" and 15 and I smoked and he had a birth weight of over 7 lbs. When the doctor said that smoking led to low birth weight, I said good. I did not want a monster baby. And yes I had a normal but painful delivery.
That's YOUR SON not the majority of kids today....
