If you had to choose, which amongst the range of human senses is the one most likely to dredge up memories (good or bad) in that RAM called your brain?

There are five basic senses: sound, smell, touch, sight, and taste. 

Here’s my example of a good memory, evoked by music:

Hearing CCR on the radio transports me right back to my carefree college days in southern California when I didn’t have a worry in the world. When the studying was done, my friends and I would pile into a light blue ‘60s-something VW bug–it’s amazing how many teenagers you can stuff into one of those–and head for the beach for a little body surfing.

The character-building skill of using the five senses to tell a story is an important one to develop, and is much-discussed here at TKZ.

When I wrote No Tomorrows, I had to dig deep into my fear of losing a child. My parents lost two, my younger brother to a traffic accident and my younger sister, five years later, to suicide. There are sights and sounds in my world today that bring those dreadful memories careening back into my consciousness.

In No Tomorrows, Annie faces that same fear when she loses track of her small daughter in the park. As I wrote the scene, I put her shoes on my feet as she raced around the park, frantically calling Nora’s name. It was a difficult section for me to write. But as I relived my memories and looked my own fear of the death of a child square in its ugly face, Annie became flesh and blood, and in a way her fear took the teeth out of my own monsters.

Your turn! Which of the five senses takes you back in time, or causes you to remember a person from your past, or evokes a feeling of comfort?

How deep will you go into your own RAM to create a character who will resonate with your reader?

As a reader, which sense/emotion connects you to the story/character the quickest?
