I think I felt that I was very well known for my figure and needed to keep that up for my work. And I regret all of it. I felt fraudulent and very shameful.
I was doing a children's book on self-esteem, and I really felt like I wanted to shed the shame I'd been feeling - and maybe make it easier for women my age who had probably felt bad about themselves.
The biggest lesson I've learned from my children is to look in the mirror at myself, not at them. I've realized that everything I've done has had an impact on them. We have to understand that they are like little paparazzi. They take our picture when we don't want them to and then they show it to us in their behavior.
If I can challenge old ideas about aging, I will feel more and more invigorated. I want to represent this new way. I want to be a new version of the 70-year-old woman. Vital, strong, very physical, very agile. I think that the older I get, the more yoga I'm going to do.
I work with The National Center on Addiction and Substance Abuse at Columbia University. I sit proudly as one of only two recovering addicts on their board.
