From when I lived here previously, 16 years ago, there have been huge cultural changes that I've noticed.
People are now out running and exercising in a way that I didn't see then - I can remember our neighbours finding it hugely entertaining to watch me go off on a run!
There is a greater emphasis on nutrition and quality food - when I was last here, I was trying to explain to a friend that five a day didn't mean five bananas a day, for example!
Sometimes, it almost seems to go over the top the other way.
Reminds me of someone saying that if the Brits had done communism, they'd have done it right, no cheating. . .
I do think though, that children's meals and foods are the work of the devil. If a kid is always given sausage, boiled potatoes or chips, and peas and carrots - well, they're not going to magically come to a love of diverse food including lots of fruit and veges are they? (This example is of a family I worked for in NZ, every night I babysat for them - at least four times a week, that's what the kids got fed. The parents couldn't understand why they wouldn't eat broccoli. . . he was a flipping chef. But I've seen it over here too, with chicken nuggets, chips, and the token serve of peas, that don't get eaten, pretty much every night. . .)
