am i old enough for wrinkles?

I'm 24. Will be turning 25 in August.

I recently noticed that I'm developing what most would call "a wrinkle" below my eyes.

This is not good. I must buy some cream.

I'm trying to determine when this "wrinkle" came about. It must have been recently. I am under a considerable amount of stress at work. Could that cause it?

Am I old enough for wrinkles?

Is this a sign of things to come?

I'm not ready to grow up.
