All of our senses create memory pathways and can be used to navigate those trails again when activated. I think we often fall back on the most predominant one--our sight--and neglect to sharpen our other senses. This takes a conscious effort to use all we have at our disposal and not rely simply on what our eyes perceive. I think we'll find our other faculties are actually more powerful for triggering and forging lasting memories. Engaging all of our senses will develop a richer experience we can recall more readily if we are willing to work at it.
