i don't know if i'm a medical phenomenon, but i've always been extremely good at ignoring adds. a couple of months ago, i ended up in a group discussing a mildly controversial billboard, and i was the only one that hasn't seen it. on my way home, i've noticed that same billboard was *virtually* ~5 meters away from my flat, so i must have passed by it dozens of times on way to my buss stop.
you've already learned how to ignore lots of stuff (like your own smell or traffic noise), so learn how to ignore adds as well.
