American cookery guru Martha Stewart has become the oldest model to appear on the cover of Sports Illustrated’s annual swimwear issue – at 81. When invited she told the magazine: “I don’t think about age much, but I thought this is kind of historic. Asked why she decided to join the photoshoot in the Dominican Republic, the cookbook writer said she wanted to prove that age doesn’t matter when it comes to things such as “friendship, or in terms of success. What was important was “what people do, how people think, how people act”. (accompanying image by Ruven Afanador)
