I've asked if I can link people to a post that just appeared on my friends list.
Anyone who might be interested might wish to go and read it, but I'm thinking particularly of people with an interest in pain management (the_major?), arthritis and dodgy joints (seph_hazard?) or sports massage and therapy (darth_tigger?)... as well as anyone else who knows what is meant when someone mentions Spoon Theory (goodness me, half of the rest of my friends list).
