What I meant was, that if children are eating too much of the wrong stuff and, combining this with a lack of excercise then how will it affect them in later life.

I say this, because a while ago I saw footage of working class families from the early 1900's. In all the hours of film I never saw one fat child.

Now admittedly we have gone from the sublime to the ridiculous, in those days health care was poor and diet restricted, but how much worse (and what life will life expectancy be) by going to the other extreme?
