re: #94 Dread Pirate Ron

My daughter who is now a HS biology teacher bought us a pulse/oximeter at the beginning of the pandemic. Oxygen has always been up but I play with the pulse rate for biofeedback. I’ve found if I manipulate my neck vertebrata back in line (I stood on my head a lot as a kid and now they look like deformed alphabet blocks stacked) I can lower my pulse rate 4-8 bpm.

Constant low-level pain?
