Misao Okawa, the world's oldest person, celebrated her birthday with family at her Osaka, Japan, nursing home on Wednesday, a day before she officially turns 117. In the past, when asked to share her secret to long life, she has cited sushi and getting a good night's sleep. This year, she simply said, "I wonder about that too."
