I'm not bragging, but I doubt even at even weight you have the experience or training.
Maybe not experience, but at even weight I would have age on you, 40 is pretty old!
Do you compete in Karate or Boxing? I have tried to watch Karate but like Taekwondo it looks ridiculous and I'm left wondering why the hell these people are not just competing in K1 (I secretly know that the answer is because they would get destroyed)
What was the injury?
