I came across the Technique when a neighbour described a profound experience - an Alexander Technique lesson. Having run a furniture making business since 1984 and being in a lot of pain at the time I booked a lesson and had my own profound experience as I was walking home afterwards. I remember stopping, lifting up and looking at my arms and realising that all the pain had disappeared. I had weekly lessons in the Technique, starting a fascinating exploration into how I worked both physically and mentally and was able to continue furniture making whilst supporting my entire system and especially my back with the Technique.
Here are some useful links to websites about the Technique:

www.atstudio.co.uk The Alexander Technique Studio. The excellent teacher training school in south west London where I trained.
