“(I’m) not skiing. Too nervous I might throw out my hip or knee replacement but if we come back next year I’m gonna bite the bullet and do some easy slopes. I did walk up Buttermilk Mountain in the snow, ascending from 7,500 to 10,500 feet. It was challenging because I haven’t been working out for two weeks (and) it took two hours. Oh boy, was my body sore that night!” Actress and fitness fanatic Jane Fonda climbed a mountain in Aspen, Colorado over Christmas.
