Perhaps the long hair makes him look older? Hard to say. Perhaps you always had a baby face like I have and people think you are younger than you are. My daughter-in-law swears she always thought I was younger than my 66 years. Personally I think she is just being kind. 8>) Not that it matters because it’s how you feel, and I feel much older than 66. LOL.
I have no wrinkles, which helps a lot.
