The human being has the ability to make relationships between palates and odors and certain situations. For example, if you eat special chocolate one particular night, when you eat that chocolate again again, you may remember that special night, even if it happens many years later. Another example, some people like to try a candy flavor to study a subject and suck the candy at the time of the test to help remember, because the brain makes the association between the taste matter and the taste of the candy.
