I was down in Bournemouth a few days ago.
I was sitting by the pier and a family walked past me, mother, father, and two children (about 10 or 11 years old - boy and a girl).
The mother was HUGE (the father a bit over weight) and they were drinking a tin of "coke" each, but it was normal coke not diet coke - you could see by the colour of the tin.
Both children were also drinking non-diet coke, and both were REALLY over weight.
I sat there and thought what hope have those poor kids got, already overweight at 10 or 11, with parents who probably have no idea about calories, fatty foods, bad diet and so on.
The parents did not look too "bright" and you do wonder even if they were taught about good diets and so on would they even take any notice of it.
Those two kids will probably have a "weight" problem for the rest of their lives.
