Best book I have read in quite a while. All the things we were taught about shoes, exercises, what we should and should not do when we get older (50+) have been WRONG! I first suspected this when I was told by a fitness trainer that I should get a shoe that would help me balance, and that I also needed orthotics to prevent a recurrence of plantar fasciitis. It occurred to me after a while that the shoes were doing the balancing for me and that my muscles were no longer needed and not being used. In short, they were wasting away. Recently, though, my pilates teacher started talking about Katy Bowman and Dynamic Aging, and how we have been taught to avoid things as we age (obstacles in house, throw rugs, climbing ladders) and not taking ANY physical chances because our bodies just couldn't handle this any more. Well baloney and cheese (sanitized language for Amazon!)!!! I will be buying this book for my best friend and others. Just disappointed that the price has gone up so much since I bought my first copy in March, a month before Katy Bowman appeared on the Today Show...Guess that's the power of TV, but I'm so glad she is able to spread her message to a much wider audience. I also feel this book would be very useful for parents of young children, to get them started on the right (foot)path because our bad walking, exercising and standing habits were learned as kids
