Zelinda Paglieno, who turned 102 in October, offers sobering advice when asked what's the secret to her long and healthy life: "Two fingers width of red wine, and no more, at lunchtime every day.” 

“I’ve never smoked, but a little wine is good for you — and that’s something I still do now. We have very good grapes here,” she explained. Paglieno’s age is no anomaly here in picturesque Sardinia, an Italian island in the Mediterranean that is home to the oldest people in the world, according to researchers on aging.
