Chiropractic is attractive because it's stood the test of time.
Many forget that "modern" medicine is relatively new. Many of its most popular (and profitable) drugs and procedures are often the subject of recalls, unintended adverse reactions or rushed to market with success rates that barely exceed that of cheaper, side-effect-free placebos.
This is in sharp contrast with the scrutiny, longevity and proven history of the discipline of chiropractic.
For over a century, chiropractic care has been pressed into service to revive the self-healing capacity of those who have exhibited virtually every named and unnamed disease or health condition. And while chiropractic care is NOT a treatment of any ailment or illness, it has never been the subject of a recall or even warning label.
While the limitation of matter or other constraint may prevent the wished-for outcome, reviving one's ability to self heal will never go out of style.
