Like most people, I am sure, in the morning I brush my teeth, shave, get dressed, and in my case have to take a few tablets and an insulin injection. But this daily routine is not without some engineering considerations. For example, I have a glass of water with a fizzy vitamin tablet with which I wash down the tablets I take. So I ensure I fill the glass with water and put in the tablet after brushing my teeth - that is because, by then, the cold water is running nicely cold, and that is nicer to drink (I have mains drinking water in the bathroom). But I don't do it later as the tablet takes a couple of minutes to dissolve and I would be waiting for it when taking my tablets. So a bit of critical path analysis involved in ensuring I am not waiting an extra 10 seconds watching something go fizz in a glass.
I ponder why I am annoyed by a few seconds waiting for a tablet to dissolve. It does not matter. The whole process is not critical - I do not have a set time to get to work, and I get there hours before anyone else most days. What seems most inconsistent is that this whole highly efficient daily routine often follows an indeterminate time spent relaxing in a hot bath. That is also time doing nothing but which does not annoy me.
I can only conclude that people are strange, or that at least I am!
