Jessica Simpson has taken on many personas in her 29 years — from virginal pop princess, to naive newlywed, super-sex Daisy Duke, and self-loving explorer of beauty ideals. On the eve of her 30th birthday, the singer plans to re-create herself again with a new health regime. She says she's shocking her system with a vegan diet, healing tea, and cupping. I hope there's room for at least one glass of celebratory champagne. Whether or not you're the type of person who goes all out for every birthday, when you approach a milestone, say 21, 30, or 40, do you celebrate in a special way and evaluate where you're headed?
