In the late 80s when I had severe, chronic muscle pain, I sometimes would lie down on the floor next to our team meeting table and just yak away just as I normally would. People are very good about understanding such stuff. It's good if the floor is at least minimally clean (i.e., not actively repellent).
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
