I grew up in Manhattan in a 16 story building where we lived on the second floor. For most of my childhood, I took the “back staircase” up two flights. When I was a teenager the building switched the old elevator with a brass panel and little black buttons to a new one with an aluminum panel and backlit large buttons and that seemingly increased the speed of the elevator 3X. Maybe I became a lazy teenager but I think it was the speed of the elevator that caused me to start taking the new elevator more. Speed matters.
