I was once fortunate to meet the eminent Japanese researcher Dr Masaru Emoto. He is famous for investigating the potential psychic retention qualities of ordinary water. Through clever experiments he has produced a compelling argument in favour of the idea that water remembers mood. It is not quite as simple as saying that if you smile at your tap it will give you a drink that makes you feel better but that's not so far, either, from his basic idea. Just be aware, this week, that what you give out, you will get back.
