Contagious?

During another sleepless night I got to thinking about somthing that happened recently.
The other day I was in Sainsburys near where I work. The lady who served me licked her lips, not in a sexual or provocotive way, she just licked her lips. Immediately I was hit by an overwhelming urge to lick my own lips.
The same thing happened later after a colleague licked his lips. (Definitely not sexual or provocotive!) Again, the desire to lick my own lips became insatiable.
And so I ask this question;
How many times have you licked your lips while reading this entry?
