The emergence of Medicare, Medicaid, labor unions, private insurance companies, etc. resulted in care being based on formulas -- not individuals. Likewise, the significant medical and scientific advances in testing and treatments have saved countless lives but further distanced patients from their doctors.
The older we get, the more likely it is we need doctors. Finding the best physician, or other healthcare provider, can become a challenge no matter what your age. It's particularly challenging for midlifers and beyond, however. You may be older than your healthcare provider, have more complex medical issues, or be used to a model of care that is no longer followed today.
