Hi, I can relate too. I practised ITF style TKD in the 70s/80's, then karate in the 90's and through to 2013. Now I am 62 and have restricted hip mobility and back issues, but I feel drawn to join a TAGB TKD club where I now live. I think I have to accept that rank progression may be limited, butbthatvwon't stop me loving it (as long as I can make it through each lesson!). Good luck but listen to your body....😊
