When asked by W about aging, Demi revealed that while “things do change” she has learned to accept the aging process. “The biggest difference, I think, is that I’m not in nearly as good shape physically as I have been before, and I have skin going in a direction that I would prefer it not go. There are things that just come with getting older. But I think my big mantra for this year is about acceptance,” she said.

2. She Exercises at Home

After forgoing exercise for "over four years” Moore recently discovered The Mirror and started taking classes via the at-home fitness tool. “My maiden voyage with @getthemirror 15 min at level 1. That’s doable after not working out for over 4 years right? I am stalling!” she wrote in an Instagram post.

3. She Is Sober

Demi maintains a sober lifestyle. During an interview with Harper’s Bazaar she discussed first getting sober in her 20s, relapsing in her 40s, and getting back into the healthy lifestyle in her 50s. “In retrospect, what I realized is that when I opened the door [again], it was just giving my power away,” she said. “I guess I would think of it like this: It was really important to me to have natural childbirth because I didn’t want to miss a moment. And with that I experienced pain. So part of being sober is, I don’t want to miss a moment of life, of that texture, even if that means being in—some pain.”

Demi is a longtime yoga, and tries various practices. “Yoga has many styles, forms and intensities. Hatha yoga, in particular, may be a good choice for stress management. Hatha is one of the most common styles of yoga, and beginners may like its slower pace and easier movements. But most people can benefit from any style of yoga — it's all about your personal preferences,” explains the Mayo Clinic.
