The article also talks about “chiropractic lifestyle”. I guess that would comprise healthy habits and regular chiropractic care. First, we don’t know if the chiropractors that passed away were getting adjusted somewhat regularly. I’m always amazed to talk to chiropractors and find out that they haven’t been adjusted for a year or more. If they got adjusted regularly, we don’t know if the care was precise and scientifically sound or some kind of “pop and pray” technique. Also some chiropractors get adjusted regularly but eat the worst food and smoke because they think that as long as “innate is flowing” they are going to be just fine.
I would like to add that even if it is not possible, now or in the future, to measure if “chiropractic adds years to life” for a certain population, it does without a doubt add years to life for specific patients. I’ve been in practice for 6 years and two patients, so far, have flat out told me that they would have committed suicide had it not been for the chiropractic care that they received. And I’m inclined to believe them. I’m sure that any chiropractor that has been in practice for a while has either experienced those things in his office or heard of such things happening in another practice. I’ve also heard of and seen numerous animals that were scheduled for euthanasia that got adjusted and went on to live for a few more years. For those people and animals chiropractic sure made their life longer. Unfortunately, most of these events never get published making it difficult to measure them.
