Thanks Walt. Pathetic isn't it? I remember a few years ago scientists spent about GBP 250,000 proving that drinking too much would give you a headache. I could have told them that for nothing!
Incidentally 'This is London' is the website for the London newspaper The Evening Standard. I often read the articles by Brian Sewell, an articulate commentator here in the U.K. He writes here on the plight of the fox in London. http://static.thisislondon.co.uk/dynamic/news/top_story.html?in_review_id=469553&in_review_text_id=423585 Other good articles here: http://static.thisislondon.co.uk/dynamic/columnists/brian_sewell.html Kevin
