I see that number combination usually twice per day.
Seriously though. the human brain is great at noticing patterns like that and picking them out of the random garp. Here is my theory on 11:11.
You probably look at a clock many times a day. When you do, part of your brain uses that info to tell you what time it is. When 11:11 pops up, not
only does the timetelling part of your brain fire, but also the pattern recognition part, so in theory, you are actually using more of your brain when
looking at this number than others that appear on the clock. This is the case only with digital clocks. You hardly ever notice 11:11 on an analog
clock.
That is my theory.
