The chiropractic cliché "Chiropractic Adds Life to Years and Years to Life" was examined for validity. It was assumed that chiropractors themselves would be the best informed about the health benefits of chiropractic care. Chiropractors would therefore be most likely to receive some level of chiropractic care, and do so on a long-term basis. If chiropractic care significantly improves general health then chiropractors themselves should demonstrate longer life spans than the general population. Two separate data sources were used to examine chiropractic mortality rates. One source used obituary notices from past issues of Dynamic Chiropractic from 1990 to mid-2003. The second source used biographies from Who Was Who in Chiropractic - A Necrology covering a ten year period from 1969-1979. The two sources yielded a mean age at death for chiropractors of 73.4 and 74.2 years respectively. The mean ages at death of chiropractors is below the national average of 76.9 years and is below their medical doctor counterparts of 81.5.This review of mortality date found no evidence to support the claim that chiropractic care "Adds Years to Life."
脊椎按摩疗法的俗语“脊椎按摩疗法让岁月增添活力，让生命延长岁月”的有效性得到了检验。假定脊椎按摩治疗师自己对脊椎按摩疗法的健康益处最为了解。因此，脊椎按摩治疗师最有可能接受一定程度的脊椎按摩治疗，并且长期如此。如果脊椎按摩疗法能显著改善总体健康状况，那么脊椎按摩治疗师自身的寿命应该比普通人群更长。使用了两个独立的数据源来研究脊椎按摩治疗师的死亡率。一个数据源是1990年至2003年年中《动态脊椎按摩疗法》过往各期的讣告。第二个数据源是《脊椎按摩疗法名人录——死亡名录》中涵盖1969年至1979年十年间的人物传记。这两个数据源得出脊椎按摩治疗师的平均死亡年龄分别为73.4岁和74.2岁。脊椎按摩治疗师的平均死亡年龄低于全国平均水平76.9岁，也低于他们的医生同行的平均死亡年龄81.5岁。对死亡率数据的这项审查没有发现证据支持脊椎按摩疗法“让生命延长岁月”这一说法。
