"Looking at a conventional watch very often a "mental dialogue" happens:
* What time is it right now?
* When is my next appointment?
* Where does the appointment take place and how long does it take to get there from here?
* Thus, when should I leave?
* How much time is left till then? Should I leave now? Am I already too late?
These "on-the-fly" considerations and calculations are not only cumbersome but often very unprecise as well:
E.g. the necessary amount of time to cover the distance is estimated too optimistically or depends on irregular, external factors like timetable or traffic situation."
I wanna tell you something, ('bout Texas Radio and the Big Beat? nah, that's for later*) this "mental dialogue" that Martin refers to, well, it's called thinking. It's fun and I really enjoy it. Does that make me crazy?
* It comes out of the Virginia swamps, cool and slow with plenty of precision, with a back beat narrow and hard to master.
