The output is somewhat related to the input.
It's quite logical to some extent.
Look at those people who drink a certain kind of water and consume a certain kind of foods, comparedss with some other people who drink some other kind of water and consume some other kind of foods, there's a difference. Of course, the gene plays a great part in there, too.

So, it kinda reveals some traits of a person by those tv series he/she watches.
Too linear, isn't it?
