If one has no sense of humor, one is in trouble.

Betty White’s memoir "If You Ask Me (And Of Course You Won’t)" was published when the beloved late comedienne was 89 years old. White, who would have turned 100 on January 17, preserved her positive and jolly attitude over the course of a more than 80-year career. To her, humor and gratitude went hand in hand: As she wrote in her memoir, “Old age isn’t for sissies… but if you are still functioning and not in pain, gratitude should be the name of the game." It’s a comment that brings to mind a favorite line of White’s alter ego, Rose Nylund, the character she played on the long-running sitcom "The Golden Girls": “My mother always used to say, ‘The older you get, the better you get, unless you're a banana.’”
