I didn't read the article, but I figure it's the one that points out studies showing low bone density in cyclists. That's pretty old news - I saw a study about it sometime in the late 80's, and a big one that was covered in Bicycling about 4 years ago or so.
Main things I took away from that were the reaction letters from cyclists the following months (with reference to the Bicycling article). They said the article made them go get scanned and they did and an overwhelming majority found that they had abnormally low bone densities.
The "cure" is to work in weight bearing exercises such as running. I try to get on the treadmill 1-3 times a week in direct response to this.
Seeing as how CC keeps breaking bones every time he hits the deck (which is as often as a cat 3 from what I can tell) I would say he needs to work in some weight bearing work. ....
....that or it is just weak bones from old age.
+1 for cyclepsycho. I spend a lot of time in steel toes on concrete.
