I started TKD one month ago with my son. I am 39 and my son is 7. We started in the same class and yes, I was the tallest and oldest there. I felt pretty stupid at first, but one way of looking at it is that it should be a good inspiration for the young ones.....if an old "fogy" can do it they should be able to. My son was not quite ready yet, but just yesterday (Saturday) I experienced my first promotion test and now I have my orange stripe. Another adult just joined the class so at least I am not the only adult anymore (but I still am the oldest). PS- at the promoyion test, there was a 5 year old boy who was awarded his blue belt/red stripe...... I am not sure why there arent more adults involved, I am hoping as I advance more, this will change. Maybe as other adultsa watch me take my promotion tests, it will inspire them to get with the program.
