Knowledge is power and power gives you better odds of surviving anything, but you seem to think knowledge only means academic learning and there lies one of your mistakes. Knowledge is not limited to facts and information. There are skills which no amount of reading will give you. If someone is going to beat your face in with a crowbar, no amount of intellectual learning will help you.

Furthermore, martial art is a lifelong journey of learning and it's not all about being a fighter. It is a way of life that you seemed to not to understand.

My grandmaster has a Ph.D in physics and a master's in mechanical engineering. My brother is a medical doctor and a 3rd degree black belt in karate and he still does both all the while being a husband and a father. In my life's journey, I've met surgeons, writers, nurses, engineers, paramedics and even a chef who all kept with their training from before, during, and after their college and medical school days. I don't see them "retiring" from anything. If anything, they seem to be going even stronger than when they were younger.

I wouldnt retire for that long. I have managed to get a PhD, work, pregnant with my fourth child and come back from a severe back injury and still train.

You say its so important to have a good mind with knowledge but the key to a long healthy life is to have good "body" and mind. seems to me that you have neglected one. That being said martial arts is key to most of the knowledge i have acquired in my life.

I think you left the path in life you wished you stayed on and staying here wondering what you should do is not getting you back onto that path. Take the next step and commence the journey instead of talking about it

Yes. If you are dedicated to an art, then why to retire? Studies are never an excuse!!! That too for 10 long years! Its good to be jack of none and master of one.. if you are good at TKD then why do quit and learn something else? No art is superior or inferior. It depends on the practitioner.

I was a tkd practitioner before, I retired 10 years ago,but before that my skills as a fighter was really awesome and I know even a lot of people know that I can turn myself to a beast if I pursue training, because I knew and they knew that training is everything to me nothing else is important, but the reason I retired is I don't want to neglect my studies I have to become knowledgeable because knowledge is the best weapon I can ever have in this tumultuous time, but I still contemplate, what happen if I continue it, I don't know the answers but all I want to say is, I realized that it is not good to be a pure tkd fighter but to learn a lot of martial arts, such as Judo , Muay Thai, Chinese Kungfu, Krav maga, jiujitsu, boxing, and a lot, I am really really confused why is it that it's just now that I think about it now that Im aging, if you are in my position would you regret retiring for that long?
