There’s very little evidence that “preventive” actions make a difference, especially in those over 65.

Bone density scans also are highly recommended but other measures (e.g., muscle tone, ability to rise from a chair) predict fractures more and bone density doesn’t predict hip fractures, as discussed here. I’d like to see references to articles showing that people on meds for cholesterol, high blood pressure, etc., actually experience different end points than those who are not screened. Often when you actually read those articles you find the relative differences are huge but the actual differences are barely noticeable. When you start quoting journal articles to doctors the conversation changes.
