I totally agree with you. Everytime there's a post on "How to increase bone density" there's always a sales pitch at the end. I will be 74 in March; walk 2 miles everyday; have numerous stairs in my house and I have more energy than most people 10 years younger than me. I eat healthy most days; love veggies, eat cottage cheese and yogurt.
I have never broken any bones yet; and hope to continue on that path. Appreciate your input. Good luck to you and wishing you many more years of health and happiness.
