Small details are the most stimulating. Why do you use a certain brand of paper towels or wood polisher? Each of these choices are connected to minute memories from our past. While triggering a reaction, a scent can send us virtually time traveling. Revisiting our past and rewriting it as we see fit so with future visits it will seem even better. That can make future choices troubling because we are basing them on a false narrative of the past triggered and rewritten to grandiose heights. Nostalgia is a bitch.
