Lessons learned from the house logs. Humans naturally have a quite poor sense of time. Humans can remember the details of what they did just fine, but remembering the time, that is a bit harder. Also, I must note, some animals such as mice and rats do indeed have a better sense of time than humans. For huamns, sure, it is the industrial revolution that largely improved human sense of time throughout the day, and computers, well, of course the modern machines have no problem with sense of time.
The common human colloquialism for being bad at judging time: saying “it seems like it happened just tomorrow” when in fact something happened over 20 years ago.
Wondering how you can detect information about the shape and geometry of pre-installed cables or cable paths? One idea: Use high-frequency signal reflection in a wire to measure its length. With very precise signal return timing, you can calculate the length of wire until the termination point. Measuring the path of the wire is, of course, much trickier. However, with high frequency signals, you can measure radio frequency emission strength at various points throughout the room to determine what zones are closer and further from the actual cable path, so long as the wire is not cased in conduit.
