Explanation:

Heinz Valtin, MD, concluded that the common - held "8x8" rule (drinking eight 8 - ounce glasses of water a day) is not medically necessary. There is no scientific evidence to firmly support it as an absolute requirement for good health, but it's not a baseless myth either as proper hydration is important.

Answer:

It is not medically necessary
