"I've always believed in a rainbow diet. As many colors and foods as you can eat, the better, because if you focus on one food, there's bound to be a report that comes out that says, 'Broccoli actually... ' So I mix it up a lot. And I take vitamins, like Biosil, which I take for my hair, skin, and nails."

"My smile has been my ticket to the world. Smiling releases the same feel-good hormones you get jogging. Caring for your lips and gums is important. I brush my teeth morning and night, alternating toothpaste brands. In addition to flossing, I use a Water Pik to massage my gums and remove food particles."

"Smile. It instantly lifts the face, and it just lights up the room."

"We decided to try in vitro, because both Peter and I felt we couldn't handle another failure. When I miscarried after that, we had to come to terms with the possibility that this wasn't meant to be."
