Rockford Alexander Technique: Who Can Benefit?

It is normal to wonder about what sort of problems can be alleviated with lessons in the Alexander Technique, or Work as we prefer to call it. There really isn't a definitive answer, simply because problems don't always follow a linear pattern. If I said my hand was hurting because I had been hitting it with a hammer, you would say, "Then stop hitting it with a hammer!" That's an example of a linear pattern. But if you came to me and said, "What can I do to fix the pain in my foot that occurs when I play the piano?", and if I told you to stop stiffening your neck, you would think I'm crazy. It is hard to see the connection between the foot and the neck.
Nikolaas Tinbergen, who received the Nobel Prize for his work in animal behavior, discussed his study of Alexander's work in his acceptance speech. After he and two other members of his family subjected the work to scientific scrutiny, he was able to say, "we...notice, with growing amazement, very striking improvements in such diverse things as high blood pressure, breathing, depth of sleep, overall cheerfulness and mental alertness, resilience against outside pressures, and also in such a refined skill as playing a stringed instrument."
That sounds like the process of lessons is actually triggering events that manage essential adaptive functions. If these essential functions are operating well, can you see that nutrition, elimination, oxygenation, rest and self control all have the potential to improve. Does this sound like an overall decrease of stress in life? Are there any problems that people face that don't relate to one of these areas?
