Guess My Age

Yesterday, during a committee meeting, my age came up as a topic of discussion among a couple of new people. Not negatively, but rather of surprise. This happened to me a few weeks ago when I was visiting DC for work with another set of folks. It's got me wondering if I look my age or not.

So here are four of the most recent photos of me, taken within the last few months. I'm just curious how old you think I am (and you guys who actually know should put down how old I look versus the real thing).
