Smells evoke the strongest response. The “Proust phenomenon” occurs when a certain smell evokes a specific memory. Odor-evoked memories are more emotional than those elicited by the other senses because of the direct neural communication with the brain.
Certain disinfectant smells evoke memories of the junior high locker room. Not a pleasant memory even after 40 years.
I love the smell of low tide. This evokes happier memories of spending summers at the ocean when I was just a tyke.
Chocolate doesn’t seem to evoke a memory response. Chocolate is more of a to hell with delayed gratification eat me now type of response. The absolute best live in the moment approach to life.
