20. Dick Van Dyke (Born In 1925) – Mary Poppins, The Dick Van Dyke Show

Dick Van Dyke danced across London rooftops in Mary Poppins and made America laugh for five seasons with The Dick Van Dyke Show. More than 60 years later, he's still the same cheerful showman.

He turned 100 in December 2025 and has credited his long life to staying active, keeping a positive attitude and dancing whenever he gets the chance. He even made a cameo in Mary Poppins Returns in 2018, tap-dancing on a desk at 92.
