Not many people can say they’ve hit the century mark, but Dick Van Dyke can. The legendary actor has been gearing up for his 100th birthday, which finally arrived on December 13.

In celebration of the milestone, Dick opened up to Good Morning America about his remarkable life and what he believes the future holds for him. "You know I played old men a lot. And I always played 'em as angry, and cantankerous," he said. "It's not really that way. I don't know any other 100-year-old, but I can speak for myself."

The actor revealed that he feels great physically, noting that he hits the gym three times a week and that his wife, Arlene, is "a health nut." "I'm so lucky. I don't have any ache or pain," he shared. "I think that saved me from the pain. That's good advice for anybody."
