Hi@hilclan When I worked I had a desk job, but got up and walked every chance I could and took walks at lunch. In retirement I rarely sat during the day, but 1n 2020, I came down with an autoimmune disorder, PMR, that made physical activioty incredibly painful, pain on a scale of 10 out of 10. I managed a long walk in the mornings, but spent the rest of the day on the couch, only getting up to cook and do necessary chores. In my youth, although I exercised, I didn't pay much attention to bone health. Thank you for your insight.
