9. Jamie Lee Curtis
Jamie Lee Curtis' birthday is on Nov. 22, and she believes that the older she gets, the more vivacity she feels. When she turned 50, she shared, "I feel more vibrant; I'm more active than I've ever been. The F-word really is freedom. It's the freedom to have dropped the rock—the rock of addiction, of family, of comparisons with other people. It's being fit and focused and kind of furious."
