My 80-year old mom is sitting at the kitchen table dissecting a banana as if it was a biology specimen under a microscope. I watch her for a few minutes intently before I ask her what she is doing. With a scientific look of Eureka discovery on her face, she tells me, she is looking for worms. Worms? She is 100 percent sure; the bananas I just bought at the grocery store have worms, especially since they had ripened enough to be extra sweet and mushy. She is peeling away and separating the banana core into smaller segments, believing that the tiny white fibers are worms.
