At 76 I still have remarkable balance and agility. My brother and I were semi-vaudevillians who performed as an acrobat team in the 1950s. We were, as one big b&w glossy poster put it, “National Network TV Stars.”

I still know how to fall but no longer have any backup muscular strength. AND, a fall now affects more strongly my entire musculoskeletal system. An injury on my right shoulder might once have been just that, but now it works itself down my right side in several places over time as pieces each react.
