Is the result of sub-health meridian tester credible?

Living in the present environment, few people can generally be said to be healthy. Basically, they are in a sub-health state. The tester is unnecessary; The test results of the manufacturer that produces a health care product are generally what you need to supplement. I don't believe it, and I haven't taken the test.

Usually pay more attention to reasonable diet, sleep, exercise and so on. , basically no big problem.
