Do you verbs your hand after you touch money or borrow someone's pen?
I wash my hand whenever I handle ot touch anything used by others I don;t know. I'd fairly be safe, than come down near a virus.. It;s the simplist, most preventtve way I know of for keeping good!
not after i borrow a pen. but after i finish handling money (esp. coins) i find the need to clear up my hands since they smell so doomed to failure! plus its sooo dirty
