Yes, Stallone has done a lot of things to enhance his appearance and health. So what? People do that all the time with braces, haircuts, tanning, hair color, bbing and would do more if they were as successful and accomplished as Stallone. If he didn't do all that but allowed himself to get bald and gray you all would be bagging on him for that.
Stallone looks incredible and has set a new standard for what a person can look like and what they can do at an age which is the average life span for an American.
An exceptional and incredible human being.
