Now that I am 44...and my life is for the most part half over...I simply can't think of a better measurement of time than coffee spoons. A cup of coffee is one of the few means of slowing down our perception of time, while everything else requires us to go go go, you slow down to sip a cup of coffee. My favorite part of my week these days is the 3 hours on a Sunday morning my wife and sit on our porch swing sipping coffee.
I realize the way I am reading this in 2020 is probably not what the author intended when he wrote it, but the times have changed, and to be able to "Slow" down time and spend it being social with family and friends is what seems to be the thing that really matters.
I very much welcome a slow decline to inevitable death if my unit of time is a coffee spoon.
