I have a shower in my bathroom but I’ve never used it. I’m a bath person. I believe that shower people are feckless and devoid of moral fibre. Baths are excellent for thinking. Archimedes knew this and so should you. One of the most powerful men in the world – the chairman of the US Federal Reserve Alan Greenspan – has a two-hour power-bath every morning at 5.30 am. Good for him.
