I am 36, I currently study a mixture of tang soo do shotokan, and boxing! Shotokan and tang soo do are almost identical but I enjoy the mix up of some of the stances and such... Anyways I practiced tae kwon do on and off for many years. Itf and wtf by the way but hold a 6th rank in wtf, main issue is I moved a lot, i was looking for a school and came across a little karate place in my area, I had been to a big we'll known tea kwon do place to talk with them and didn't care for the general attitude, but the karate place had a vibe that drew me in, the instructor was so interactive with his students, and seemed to show the techniques often, jumping kick or whatever. Sorry to ramble on about me lol but my point is that I attend the karate school even though it is different then what I knew, and had to start from scratch, the point in that is it isn't the style it's the school/teacher that are important. There's good schools and bad schools, and same goes for instructors and general vibe and attitude of the student body! Hopefully you find a school that's right for you, no matter what the style! Take care.
