Oh, I see the word body that I used sounded misleading. I just wanted to highlight my dislike for the people who have lived for like 40 years and more in this world but still have the brain of a 10 year old. They call it youthful, I call it retarded.
I did not mean to say anything about the looks of the body. 40+ years old body is always old. It can be healthy, and stronger and nicer than most teenagers, but it is old nevertheless.
Jack is cool in his mind and body, too.
