>>14273662This of it like this: let's say you wanted to ask if any one person you meet likes green tea. So you go around and ask all your friends, and you realize that approximately 50% of people like green tea 50% dont, and if you went up to a stranger it's a coin flip whether they like it too.
From a different perspective you realize that Green tea flavor is determined by how your taste buds/brain are wired, and that trait is genetic, so if you test a stranger you can tell with 100% certainty whether they like it just by looking at their DNA.
