15. Microarchitecture

On the left are the rail-less granite slabs that serve as steps leading away from my back door (the steps continue unseen to the left). This angle demonstrates the steep drop from the top step to the bottom of the window well outside a basement window, about six feet.  

So there I am on the that step, standing on one leg while I put on a shoe, when I lose balance and fall into the well.  It's a slow fall and I think as I fall, "shit, I'm probably going to break the window; a real pain to fix."

I should have been more worried about breaking me, given the state of my bones.  A few months later, the hinge on my folding bike breaks and down I go.  But again I remain unbroken. Many people with osteoporosis break a bone just standing up or sitting down. Why didn't that happen to me with two hard falls?

The answer may be a concept called microarchitecture.  I may not have density, but there is something protective about what little structure I do have.  Sounds like a theory made up to explain something that can't really be explained.  Whatever it is, I'm grateful for it.
