Yes agree merlogran, it's a perfect storm of several factors, electronic gadgetry that makes people, including children, more sedentary. Like many, my own childhood was one that was active, our generation weren't cossetted we were allowed to roam free and we did. TV was limited to children's hour, we drank water instead of fizzy drinks, meals were cooked from scratch on a "take it or leave it" basis and vegetables were always part of that meal. My parents didn't provide any snacks such as crisps or biscuits. In between meals we may have been offered an apple or banana, but there weren't a lot of grazing options. MacDonalds and the like had yet to arrive, there were Wimpy Bars but I don't think many of us during our school years had enough pocket money to buy a meal out, the pocket money did stretch to sweets and chocolate which I can remember spending some of mine on. We didn't worry unduly about our appearance, in so many ways it was a lot easier and strangely fat kids were rare!
