Is it normal to miss my teenage body?

Present day I am a 33 year old man. When I was 16/17 I feel like I was in my best shape. I was very good looking, very popular at high school, was the best at any sport I played, dance in parties, dated the hottest girls in my class and wasn't over burdened with responsibilities that I am today. Today I am become kinda fat, cant hardly get a date or do many things I could do as a teen like climbing trees and have a permanent back pain and am diabetic. Ofcourse it is possible to be in good shape in my 30s, and even later in my life (we live in a age where 80 year olds can win marathons). But what I could never have back is my good looking slim teenage figure and all the fun stuffs a teenager enjoy (I still find teenage girls attractive, but its completely immoral and unethical to engage in relation with them, let alone dance with them something I used to enjoy so much). Also many activities I do now were much easier to do as a teenager, staying fit as a teenager is far easier than staying fit at later age.

Now what I really miss is my teenage body, not my teenage self. I know how arrogant and stupid teenagers are, and I was no different. I did extremely stupid and hateful stuffs that I truly regret ad can never forgive myself for them. I would never want the mind of a teenager again and never have to engage in the stupidities I did back then. But if it only were possible to return to my teenage body of 16/17 with my present mindset and knowledge of the world along with all the degrees I have earned ad stay that way for the rest of my life (never physically aging past 17, but aging only mentally), then life would truly be wonderful.
