How Academia Ruined Dole Whip

I was reading an article about how mood can affect your perception of products. So if you're happy, you think the product is making you happy and so you like it more. It made me start wondering if maybe I really like Dole Whip because I'm happy when I eat it (at the state fair, at Disneyland/World). Next time I have it, I know I will over analyze whether I really like it or I just like where I am. ::sigh::
