I've wondered the same thing. I'd quit eating toast for breakfast in the past, and during those times, the smell of anyone else in the house toasting bread was just intoxicating to me. At the time I remember thinking it smelled even better than it tasted. Now it doesn't smell that great....certainly nothing compared to my bacon, eggs, onions, tomatoes, and kale! Maybe that's the key for me--my taste buds are so excited by primal food that the old stuff is just blah.

Primal since July 2010...skinniest I've ever been and the least stressed about food
