Hello,I'm going to be 14 years old in september and i asked my MA teacher about Muya Thai, he told me that when i will grow up a little and my bones will be harder,he will teach me Muya Thai. How old I must be to start Muay Thai? And is it dangerous(I don't mind full contact sparring) just not breaking bones. And is it effective in a street fight(not ground fight).
P.S My sensei is the leader of Georgian MMA Federation. He teaches us Shotokan karate right now.
