after taking TKD for almost 4 years, and after much abuse to my body, i started looking for an art that i could do with my kids. i visited an aikido dojo here and found out that they don't do punching or kicking, that it's more self defense. honestly, i thought 'how hard could this be'? WOW. very different from TKD, and it has been hard at times to learn some of the techniques. 9 months later, all in all it has been very rewarding. visit some of your local dojos. a lot of places will give you a free lesson, or sometimes a free week of training to see how you like it.
