I was sitting at my desk for hours reviewing abundant requests (extra requests during QA stage!) from a client. Just before my get-off-work time, I felt a mild lower back ache, felt like getting a back massage but too bad I don't have the time for this luxury.
Soon it was class time. After a couple for hip-opening and twisting poses, I felt much better, so much relief for the lower back.
I love Yoga, for its self-therapeutic effect.
