Many of my old steel bikes from CA have been shaken to dust since I moved to OR twelve years ago. I've even had a couple of racks break from the bouncing.
Actually, I probably developed the boat anchor bones from many years of basketball. I finally quit playing in 2000 when it became apparent that my dunking days would soon end. The game just isn't as fun below the rim. My knees have been thanking me every day since then.
Well, those bone-shaker roads are among the reasons why your bones are so healthy, I would suggest.
From my understanding, it's the impact that encourages bone density, as in the leg bones, for instance, resisting force as the feet hit the ground running or walking. Weight lifting, to me, is not what this about because the muscles, tendons and ligaments are tending to take the load, rather than the skeletal structure.
