Memory is a strange thing. I was thinking about this the other night in the context of a few simple math facts that have somehow always alluded my memory. For instance, whenever I have to mentally compute either 7+5 or 8+5 I really have to think about it. I’m not quite sure why. My conjecture is that I was absent from primary school on that particular day, and simply never recovered. I had a similar experience with the lower-case cursive letter “k”.

Does anyone else out there have a similar experience? I’m sure that this phenomenon is fairly universal. Science is teaching us some amazing and unexpected stuff about how the mind works, and so I suppose that it’s not surprising that sometimes “easy” facts escape us.
