I did a test today, and contrary to what someone I used to know had said that people normally cannot focus beyond two different beats I discovered - from the moment of concentration - that I could actually listen to three different sounds at the same time! One from the game, one from the radio, and one from the movie. When I told my Dad about this he said I could be a genius and asked if I have a good memory. I said quite.
This is interesting for I thought I had known myself well enough, but it seems my potential is actually far ahead of the limits of my perception.
