Control

I remember learning once (in High School during English class) that when a woman puts on mascara she involuntary opens her mouth. It was sited as a muscle reflex. Of course, all things considered I took it upon myself to force my mouth close during the mascara application process. I was reminded when I was doing my morning makeup and thought "damn I have badass control over my body!"

I also stifle my sneezes...woot I'm a anti-involuntary muscle machine!
