Arguments with myself

I recently got my hair done. Someone told me the highlights make me look younger. Am I at the age where I need to start trying to look younger? I always try at work to sound more mature and dress more sophisticated, and well...older. My 29th birthday is in 6 days. Am I officially getting old? Is now the time to start buying anti-wrinkle cream? Even worse...am I old enough to be called a spinster? Ugh...thank goodness I'm at least old enough to drown my sorrows in a bottle of wine.
