I went to see the film Atlantis and was not surprised to see lots of excited youngsters in the audience.
On the following evening, I saw a McDonald's TV advert, using the Atlantis movie to attract youngsters to eat the restaurant's products. Get your Atlantis toys here, and so on.
What chance do youngsters have to resist such clever advertising? It seems that the really healthy foods are all quite boring and therefore don't stand a chance these days.
As so many ailments, in people of all ages, are discovered to be related to poor eating habits, I suppose that our medical services will be kept very busy, well into the next century.
