A dreaded disc problem is the cause of all this

 
This regular walking thing is relatively new. See, I have a herniated disc in my back. It pinches the sciatic nerve that runs down my leg. A physical therapist told me to walk and do a bunch of exercises for the next 9 to 12 months, or else face a sawbones doctor. They say this is degenerative disc disease. So I'm a walking son-of-a-gun now. Hence pictures of things on the ground, since I walk with my head down. Hence the aforepublished pictures of the dead oppossum.
