This is a great book explaining what the Alexander Technique is and offering some really basic 'lessons' although in reality they are more like a 'sampler'.
I'm HUGELY cynical of any new age rubbish but this is nothing of the sort. It's very well organised, well thought through medical/physiological advice.
Read the book, enjoy it, and do what it says. I'd be suprised if you didn't experience some suprising and very pleasant revelations. I don't want to spoil it, approach it with an open mind. I did and I really enjoyed it.
For me it may or may not lead to the formal lessons. I haven't won the lottery as far as I am aware and I don't have the time to spare but after my positive experience of this book perhaps that would be my loss.
I "walk tall" with a lot of pride for a few quid. Seriously, buy it if in doubt.
