Although I now wear a watch for many years i didn't bother. I knew instinctively what the time was to within a couple of minutes. I can set the timer on the oven and then walk into the kitchen just as the timer goes off as an example of my internal time keeping. Nothing to do with light or were the sun is in the sky, just natural instinct. I have been told that this is a good indicator of an INFP and that many INFP do not bother to wear watches because of it. Do others have this trait?
