Profile Portrait Pitfalls

So my profile picture is almost as old as my elder daughter (she being 6 in a week and a half). I keep thinking I need to update it, but there have been several hindering factors preventing that, namely my abhorrence of pictures that include me. Michael walked into the living room tonight while I was working and noted my sexiness - I look like a librarian...or Sarah Palin, depending on your political with-it-ness.

Here I am in all my Palinesque glory (albeit sans make-up, clean hair, and taken at 3am)...

Thing is, I've been doing my hair like this for years, and I've had these reading glasses longer than I've had my son (who's 8 )...
