You and seem to have arrived at the same place via different, but similar routes. I'm all for self help whenever possible. Nowadays I have embraced the Chinese approach to keep my back (and the rest of me) in good health. During an extensive stay in China I was impressed by the number of citizens, particularly the elderly, who were out in the parks every morning, practicing Tai Chi and Qigong.
I practice Qigong myself, twice a day now and I'm still fit and healthy at 79 years. The Chinese have a saying which, paraphrased goes:
'A long, healthy life begins with a strong healthy back'.
