I recently watched an episode of Comedians In Cars Getting Coffee during which Sarah Silverman explains the concept of your “default face.” This is what your face looks like when it is without expression.

Ms. Silverman says you can “change your life” by simply changing your default face. I believe she is correct. I first noticed this about a month ago when I hung a small mirror from the windscreen in the Jeep (to watch the angry motorists forced to go slow behind me). I am also able to see my own face and I immediately saw my default face. Not pretty.

But when I smile… voila! I take five (ten?) years off my face. It will take a while for this to become my default face because it takes a) awareness and b) some extra facial muscles that don’t get used that often.
