Absolutely, and part of that is genetics, as I mentioned, I think people from certain genetic backgrounds just look older and some younger. I have a son in his early 20s who could easily pull a 21 Jump Street. I could put him on my 15 year olds soccer team and no one would even question it.
In scrolling through before and after pictures I noticed many of the younger looking people really looked younger after weight loss. Some of the older ones looked better, others looked older. Note I am in my late 50s. Interestingly, other than the channel in the neck and chin area, no one had major hanging skin
