Trisha Yearwood
Age: 56
Fountain of Youth: Since her marriage to Garth Brooks in 2005, Trisha has stayed hip with the youth set by helping to raise three stepdaughters. Also an avid walker, the angelic-voiced blonde once spent three straight days walking 60 miles to help raise money for breast cancer research.
Her Secret: Trisha suggests always keeping a stocked fruit bowl and having frequent “veggie nights.” “We like to sauté peppers, onions and carrots,” she tells Health magazine. “In 30 minutes we have a table full of healthy food.”
