I think it has nothing to do with names. It has more to do with our own senility.(at least mine) What helps me to remember what I did yesterday was to associate that layover with something, i.e. the cheesy song you heard on the van, CA ripped one on short final... If drawing a help me jog my memory, so be it.

Seriously, studies have shown that writing down things is 1 of the best defense against memory loss. (Probably why most crusty old CA has like 4 pens in his shirt pocket.
