I'm 21 1/2 years old and I could literally pass for 15 years old maybe in physical outward appearance. I see Andy Milonakis...he obviously has this disease...maybe I have a slighter case than he does? I've smoked tons of cigarettes for 3 1/2 years now and drank tons of alcohol and shit...both things that are suppose to make you look older. Both those definitely made me look older but I still look MAD young. Could I have an undiagnosed case of this disease? I'm starting to think I do because I look ridiculously young for my age. Like when I buy alcohol, people don't even consider it an option that I'm old enough to do it. Would someone be able to correctly determine if I have this disease or is it just a subjective type of thing? One day looking really young will pay off...when I finally look like I'm legitimately 18 but at this point it's kind of annoying.
