I have struggled with this subject since the late 1960s after an industrial accident. I have found that physical therapy helps a lot, rather than chiropractic. I wear a back brace before doing heavy work. I stretch every morning before getting out of bed. I like hot tubs and warm weather.
Logging did not help it at all.
I try not to life more than 50 pounds. Keep moving, but use the right posture. Hanging upside down in a device helps a lot also.
Alcohol and drugs should be a last resort.
