"Are you leaving someone at home to develop the same problem you have?"
This one, from the how-can-we-guilt-or-shame-patients-into-bringing-their-family-in-for-care department, generally falls on deaf ears. Largely because regardless of what you tell patients, most subscribe to the "if-it's-not-broken-don't-fix-it" school of thought.
This reveals that for many patients, taking preventive measures before symptomatic episodes emerge is seen as a needless luxury. This myopic view is echoed by financial institutions who report that most Baby Boomers are not saving for their retirement.
So, don't take it personally!
Instead, take a more subtle, long-term approach. Make sure that every patient is aware that chiropractic helps with countless other issues than the one that prompted him or her to begin care. And secondly, provide ample clues throughout your practice environment that you see children. These strategies may not be as gratifying, but they avoid the use of guilt or shame and are considerably less manipulative.
