Glenn Reynolds cites the very long lives of some California winemakers, such as,
Ernest Gallo (EJ Gallo Winery): March 18, 1909 to March 6, 2007Glenn ends by writing, "I don't think this supports any scientific conclusions. But why take chances?"
Tchelistcheff (Beaulieu Vineyards): Dec. 7, 1901 to April 5, 1994
Actually, Glenn has it the wrong way round. These long lives alone cannot form the basis of a scientific conclusion, but they do support such a conclusion, once drawn.
However, the jury is still out on the question of whether resveratrol, a chemical in dark, red wines, makes you live longer. But it seems to be looking good so far.
