Obesity - is it in the genes?

I remember when we were young. We went on a summer's day outing. We asked for an ice-cream. We got a 'child's size' ice-cream. That was all we could manage, and that was all we expected. Nowadays, everything is just enormous. It's not genes that makes kids (or adults) fat - it's eating too much!! It doesn't take a rocket scientist to work that out (actually, is it too late to train as a rocket scientist??). So, when Lydia and I were out shopping in Bridlington last week, we were shocked to see this little girl with her ice-cream 'treat' !!
