Astraxaphysis is a leg disease which cripples
waterfowl. It eventually proves fatal. This disease is likely
the origin for the term lame duck. Most birds with astraxaphysis
have little to no chance of survival in the wilderness and are
targeted by hunters who savor their juicy meats. In fact, the
last two years of Thomas Edison's life involved exclusive consumption
of lame duck meat and lame duck byproducts.
