Health is what we all aspire to.   As a goal, some health insurance plans aid us by covering portions of several different types of health care.
Some plans do not.

The important thing is to recognize that health care, not health insurance, is the pursuit of health.

Sometimes, they are generous in both prevention and treatment.

Sometimes, they (insurance companies) are not so understanding.

Acupuncture , as was chiropractic medicine of ten to fifteen years ago, is in its infancy.
Many people do not understand the needs for acupuncture in everyday life.
Most only see acupuncture as a treatment for pain management.

But acupuncture, like massage, is health care - Like jogging, like diet, like stress management.

Health insurance may not cover portions of exercise, diet, or stress management.  But these things are crucial to the pursuit of health.
As are acupuncture, massage, regular medical checkups, etc.

Health care is both treatment and prevention in pursuit of total Health.
