St. Jude patient Calvin was diagnosed with a brain tumor that caused excruciating headaches. But you wouldn't know it because his personality never waned. Calvin never meets a stranger, he's always dancing, and he loves his St. Jude family. Today, he's back home and living life to the fullest. "All the time, Calvin asks if it's time to go back to St. Jude," his mom said. "It gives me comfort that he loves the hospital so much."
