I remember looking at younger daughter’s primary school photo for year 6 and realising that and about half the class were severely overweight, and and fair few would be classed obese.
This is in a reasonably affluent middle class area – with countryside all around. You couldn’t blame lack of opportunity or sports facilities round here either.
I am guessing that too many kids just do not move enough. If they are obese then, what hope for the future. It is scary.
