I have "military neck." That's why I've purchased your book. My chiropractor wants me to do aggressive stretching (w/posture pump, hanging weight from my head, etc.) but they just increased the numbness in my fingertips. Four years of chiropractic care didn't "correct" the cervical curve and I have arthritis in my neck, along with stenosis. Throughout most of my life I've had poor posture, especially standing and sitting (I'm tall-6'3"). Neither my chiropractor nor my orthopedist is recommending surgery, yet. What hooked me for your method were your examples showing the rather straight necks of the people you studied. Is my "military neck" something to worry about? My orthopedist made no comment regarding it. I've been working with your book for a week now and I do feel a difference overall though the numbness and tingling in my hands and and fingers isn't gone; but I do feel a lessening of it from time to time. I know anything will take time. I've been working with chiropractors for now for 4 straight years! And I am very active; I run (barefoot), skip rope, and practice karate on a regular basis. I'm 48. Any comments you have will be appreciated. Thank you. Oh, by the way, not one chiropractor, MD, or specialist ever asked me about my posture.
