Hurley starts the day with hot water. "When I got to the studio I'd drink a mug of hot water and go into hair and makeup," she says. "I often put apple cider vinegar in my hot water. It tastes disgusting. I can't face it every day, so I'll put it in my hot water maybe every other day. It's good for your metabolism. After about half an hour I have a cup of coffee, and after an hour I'll have breakfast."

Hurley tries to source her food locally whenever possible, growing her own fruits and vegetables and shopping at nearby farms. "Backyard gardening can inspire you to take an interest in the origins of your food and make better choices about what you put on your plate," says Dr. Helen Delichatsios, an internist at Harvard-affiliated Massachusetts General Hospital. "When you grow your own food, you savor it more because of the effort it took to get to the table."

Hurley keeps her workout routine simple yet effective. "I don't do any regulated exercise, but I'm very active," she says. "On the weekends I go for long hikes with my dogs. I try and stretch every day. I do the occasional yoga or Pilates class, but mostly it's just self-exercise at home. I might do some stomach exercises or some bottom or arm exercises, but because I trained for a dancer when I was young, I sort of know all the exercises. I find it very hard for my schedule to regularly go anywhere else. It works very well for me."

Hurley makes sure 50% of her diet is vegetables. "I haven't eaten processed food for 100 years," she says. "I don't eat sweets. I drink little alcohol. I don't smoke but I deeply regret that I once did. I have learned to eat lighter and not so late."

Part of Hurley's mantra of "gentle exercise and lots of it" means plenty of walking. "I walk every day, so I try and hit my 10,000 steps a day and I do some stretching every day," she says. "And then sometimes I do a bit more, but that's enough for me really."
