Howdy, I turn 50 this month and am considering taking lessons in Shorin Ryu Karate. I'm a Sp. Ed. teacher and the stress relief alone of Karate is a motivator for me, nevermind the benefit of the exercise and self-defense. I've dabbled in Isshinryu and Northern Shaolin Kung Fu over the years, but now realize that if I'm ever going to achieve any level of proficiency in martial arts, I'm running out of time. Also, I tip the scales at 280 lbs! The original post is meaningful to me. Forgive me for using my first post to revive and old thread.
