He's pretty fat and that fills out the wrinkles in your face. His current (smaller) weight is about the same as my dad's, who is 82. My dad has absolutely no wrinkles at all (and no grey hair except a few at the temples) and he would be the last person to have plastic surgery. He's also spent his whole life sun baking with no sunscreen. However if there was no face fat involved I think there would be more wrinkles.
