Because bacon is one- to two-thirds fat and also has lots of protein, it speaks to our evolutionary quest for calories. And since 90 percent of what we taste is really odor, bacon’s aggressive smell delivers a powerful hit to our sense of how good it will taste.
In other words, bacon is the easy stuff. You think you aren’t easy, until you are. There is forgiving with bacon, but not forgetting. The smell lodges itself deep within your psyche and hangs on with the toughness of spider’s silk.
Thank you LRoy.
