Massage

Getting the first rib and shoulder worked on, the therapist came out with comments like:

"Wow, you have the tightest, most ropey muscles I've ever seen."
"You have practically no movement around the rib-cage.""Have you got a history of serious shoulder injuries?"
"I'm guessing you get a lot of lower back pain."
"Have you ever been to a chiropractor?"

The advice was that I'm doing everything I can to fix my stiff old body, so I should just keep on with the yoga and the stretching, and things will improve over time.

I'm going to a chiropractor in a week.  Because i'm leaving town soon, I'll get him to write out a written evaluation of my back and what needs to be done.  We'll see how that goes.
