Famous for marrying former Beatle Paul McCartney in 2002, Heather Mills McCartney, 38, is embarking on a crusade to eliminate milk from the British diet. Mrs. McCartney credits a dairy-free, vegan diet with helping her to overcome a post-operative infection following the amputation of a leg.
According to Wikipedia, in August 1993, she was hit by a police motorcycle while crossing the road; her injuries included crushed ribs, a punctured lung, a metal plate needing to be put in her pelvis and the amputation of her left leg below the knee. She has a prosthetic leg, and was noted for taking it off and showing it Larry King on his talk show in the US.
She also campaigns against land mines and fur.
