Age-defying five-time Olympic swimmer Dara Torres is having a big week. Her book Age is Just a Number: Achieve Your Dreams At Any Stage In Your Life has just been published and today she debuts as “Dairy Torres” in a “Got Milk?” ad.

The 41-year-old Parkland mother is sporting one of those milk mustaches – she joins more than 250 athletes and celebrities who’ve worn it -- and praising the benefits of lowfat milk for women’s fitness.

“I’m a natural in water. But after a workout, my natural choice is milk. It’s a strong starting block for wellness,” her ad reads. “The protein helps build muscle, plus its nutrients help me refuel. Three glasses of lowfat or fat free milk a day. Lap it up.”

Researchers say milk helps repair muscles after workouts and improve bone density.
