This book nails the way chronic back pain gets into your head and becomes a filter through which every activity must pass. Until it became clear that this was pretty unhealthy, I used to rate the state of my back in beers or bourbons, so I got a kick out of the cocktail theme.

I got that impression. My issue is my arthritic knee and the aftermath of a complicated tibia fracture. Minor in comparison but involves similar pain and activity management.
