Claude Taittinger is sure drinking champagne every day keeps him trim. Looking at the slender 70-year-old, one can't help but agree. 'I am convinced drinking half a bottle of champagne a day will not only keep you slim but prolong your life by 10 years,' says the Champagne Taittinger head, who believes champagne and other wines can help prevent cancer and Alzheimer's disease. Claude quotes statistics that the average lifespan of the chairman of any champagne house in France is 86, while the lifespan of an average French male is 76. He believes champagne also gives him extra energy. He plays tennis twice a week and swims and skis. Claude had his first taste of champagne at 10 years, when he was given a glass of his family's champagne at his own communion. 'The year was 1937 and the champagne was a 1915 vintage. That vintage year was especially meaningful because it was during World War I and the champagne region was part of the battlefield where the French fought the Germans. Some farmers were killed while trying to harvest the grapes.'
