“I think each person has an individual ‘need’ for staying sexy,” says Davina Frederick, 50. “For some women, it may be making time for the things they love to do -- like art or dance. And for other women, it could be embodying a certain type of style.”

Frederick says that she feels sexy by staying fit. This is her key to feeling young.

“For me, I think health and fitness are the fountains of youth. Healthy, fit women feel confident -- and it shows,” says Frederick. “In particular, (I like) lifting weights, eating whole foods, drinking water several times a day and sleeping well (not always easy as we get older, I know).”

Make a list of all of the things you love to do and the schedule time to do them. This could be as simple as a “date” with yourself once a month. No amount of time invested in yourself is too little.

Joy and sexiness go hand in hand. That’s because joyful people exude a sort of “je ne sais quoi.”

Shimon says that the key to reaching this point is simple: Give yourself permission to feel joy.

But how do you do this?

“Don’t pretend,” says Shimon. “For example, in my 20s when I tried to feel sexy, it was like an effect. I was someone I wasn’t. I was being disingenuous. Now I’m just me -- and if you like it, great. If not, I’m not your cup of tea. I can let that go a lot easier.”
