Thinking about getting into an exercise routine to help me quit smoking and help with my hypoglycemia which is starting to get noticeable and I was thinking about this martial art. Figure if seniors can do it it'd be about my level being out of shape as I am. I used to do some very casual martial arts and sparing when I was part of a club in college so I'm not totally a novice.

What do you think, if you do it what's it like?
