Imagine you had two bananas:
One banana has been rotting for 4 years. It is black, moldy, and smells like a barnyard. You've even tasted this banana, and it is rancid. The flavor, aroma, and even appearance, isn't even banana-like anymore.
The second banana is past its prime, and certainly isn't a banana you would choose if there were other bananas to choose from. It is still yellow and in tact, but it has some brown spots, and is a little mushy. It still smells like a banana, and looks like a banana, though. Not sure how it will taste, but you already ate another banana from its bunch, and it was a good banana.
Which banana do you eat?
