Rockford Alexander Technique: Is it About Posture?

Recalling that Alexander's work is about education and unlearning the habits that are getting us in the wrong, let's look at a quote from his first book, Man's Supreme Inheritance.
"The first step in re-education is establishing in the pupil's mind the connection that exists between cause and effect in every function of the body."
Now that's not hard to do, especially if you did yard work all day and have sore muscles all over your body. But what if it's in the area of a sore wrist from too much computer mousing? Or what if you HAVE to produce a big paper/recital/any-kind-of-stressful-project, and you develop a nervous tic in your face?
Alexander simply says, "You did it and are actively engaged in producing those symptoms, so just stop it!"
Fine, you say, what shall I stop?
Just stop.
That's right, stop.
Now for a game.
Decide on a "stimulus" that you react to. Examples include, the telephone ringing, a particular person's way of addressing you, a dog bark, or even your own desire to stand up straignt. Now take a few days to watch how you react to that stimulus. Make notes of what you observe. The more you observe, the more you are going to have ultimate control over how you choose to respond. Do you pull your head back? Do you feel a downward pressure on your ribcage? Do you jump?
Good! Now that you have followed in Alexander's footsteps, you will want to come back to the main controlling issue for vertebrates - stop doing that neck stiffening thing.
It took Alexander about ten years to sort that out. Havinf a teacher helps considerable. Look one up. If you're in the Rockford area, here we are!
