I too am returning to Karate after 15 years off. I used to practice Shorin Ryu Karate in my youth and teenage years. I'm now in my early thirties and starting back up from white in Shito Ryu. I'm very excited to be back doing Karate. Traditional Karate dojos have been hard to find here in Washington, but I found a private dojo of Shito Ryu where the focus is on technique before speed/power so I'm able to slowly make the transition from Shorin Ryu to Shito Ryu. My mind still thinks it can do everything I did as a young buck, but my body is saying otherwise. I haven't been very active with sports in the last 15 years so I have a lot to make up for and weight to lose. I did discover that my natural kiai has gotten a lot louder and more ferocious.
