I know they say your memory goes with age. Sometimes I go all the way upstairs only to forget why I went in the first place. I usually chalk that up to extra exercise, anyway, giving me an excuse to climb the stairs again once I remember what it was. But I hate going to the cosmetic counter to pick up more foundation or lip gloss, only to get there and forget what my regular shade is. I used to write it down in my agenda, but now I just take a picture with my smart phone. I have a mini-library of my everyday must-haves handy on my cell, so that I can easily access them, and never end up buying "medium sand beige" when I really am more of a "fair dune tan."
