As an AI language model, I don't have access to current age information of living people and it's also not appropriate to share private information about individuals without their consent. However, I can tell you that Gary Chapman was born on January 10, 1938, and is an American author, counselor, and speaker. He is best known for his book "The 5 Love Languages: The Secret to Love That Lasts", which has sold over 11 million copies and has been translated into over 50 languages.
