That sounds about like me. It's a "skill" anyone can get better at; same with temperatures. Always ask yourself the question, answer it, and then check it vs. reality.John, you just reminded me of an uncanny knack my Father had. At any time of the day I could ask him the time and he would pause a moment then say something like "it's 12 minutes past 4" and when I checked my watch he was invariably within a handful of minutes at most of the actual time no matter what time of day I asked him.
I never knew how he did that nor have I ever known anyone else do it. That really was strange!
Sounds like a true idiot-savant!I also knew a guy in gaol who was as thick as treacle & could barely read or write yet was amazing with numbers! You could ask him 14 times 16 and he would tell you in seconds.....amazing!
And the gaol thing surprises me.... did you actually do time? Or a visitor, guest of the warden....?
