Makes sense. I tried to show a friend of mine how her brother looks a lot like my dad. Her brother is 30 and morbidly obese. I showed her an old photo of my dad and his family - dad was in his early 20's. She didn't see the resemblance, but freaked out because her 30 year-old brother looked identical to my grandpa, who was in his 50's and just had a stroke.  She even showed the photo to her brother, and it didn't even phase him that he looks like a 1970's middle-aged, overweight dad. Haven't seen him in a few months, but he's probably still pretty big.
