Julian Dayit's a small thing but I got through the entire winter without throwing out my back, and I think the daily stretching routines are helping.
I don't think I'd gone a year without tweaking my back since my early 30s. I'm grateful. Upper back pain sucks and is inconvenient, but lower back pain is monstrous. (C tweaked her lower back exactly once, and was like, "oh, this is what you deal with.")
