I am 5’3”, but used to be 5’5”. About 7 years agp I realized I was shrinking, so increased my boron intake from 3 mg. in the morning to 3 mg. morning and evening. I am now 84 and have only shrunk another 1/2 inch in that time. My mother, with similar weight, height, and build had shrunk a lot more, but she was not taking the vitamins and minerals faithfully the way I have for 50+ years.
At 84 and in good health, slender, and fit you are in an excellent position to give health advice. Thank you for all you do.
