Two years ago I was lucky to be invited to visit a friend who lives in Tokyo. During the three weeks I was there, travelling around Japan, I didn't see a single dirty car or a single fat person. The Japanese eat very healthily but also in small portions,eg in one restaurant we were served a single slice of mushroom as one course in a four course meal. They eat from beautiful china dishes some of which are tiny and of course they use chopsticks. Since my surgery I now eat most of my meals from small plates or bowls using chopsticks which means small mouthfuls and in my case makes eating a slower job!
