Hi bunky44, I had peace of mind for years, doing it my way with exercises, various diets, supplements, etc. My aunt actually died from spinal fractures so I feel this is nothing to mess with, but will do what I can to increase bone density actively. Prunes are supposed to be good for that - 6 a day - so I bought a lot of them today. I had open heart surgery two years ago and the surgeon said if my bones were too thin, he would use a steel plate to reconnect them, but I didn't need that then. I think the year of relative inactivity for me due to the autoimmune disorders kind of did me in. I bought an Ellison Bolt vibration exerciser after pouring over the reviews. Some of those machines are over 20 lbs. We're not supposed to lift more than 20. Good luck with the Grow Bone.
