Here's an almost totally useless "test"

Not sure why you dismiss the test as "almost totally useless", Vernon. The test is based on real science linking a person's sensitivity to taste to the number of papillae on their tongue - as explained at the conclusion of the test.

Just as digital picture quality is determined by the number of pixels, so taste is determined by the number of papillae. Odor [aroma] also contributes to taste, of course.
