Too late to start and how to convince my parents?

Question
Hi, my schools wrestling team is in need of people to wrestle and everyone on the team is telling me i would dominate at 120 since I'm 6 feet tall and I'm 16 and i was wondering is it to late for me to get into this sport since I'm a junior and i was wondering how to convince my parents to let me join, I told them how my friends think ill be good at it and they are still hesitant about me doing it. so i was wondering is there anything else that will convince them to let me join?

Answer
Well no thats really not to old. There is a couple good things about wrestling. It keeps you in shape, teaches u discipline and teaches u the vaule of hardwork. Try that. Also, you are going to have to join some wrestling summer camps so as to become somewhat decent. Wrestling is going to be hard but its really rewarding to have your hand raised. Good luck with your parents
