The Difference Between Osteopenia and Osteoporosis

There is a honeycomb inside your bones, 
its walled divisions tunneled into 
the circumference  of your wrists. With time, 

each cell grows more porous. You hope to be 
as the Pliocene whelk fossil found in Sarasota 
County, Florida—Chalky and pockmarked, 

its spiraled shape still discernible 
even as the spaces inside yield
more easily to fracture.
