I agree with the person above - when a physician sees a patient more than is medically necessary, it is called <u>churning</u>.

The patient is either healthy or not experiencing anything harmful, but the physician is still treating them although there is no viable purpose in that.

-Keeping up on immunizations
-Regular exercise
Hope this helps :)
