OK, so maybe you're one of those people who don't wash their hands even after going to the bathroom because your dad never did and he never got sick.
Or you think a three-second hand scrub is more than enough.
Or you squirt on some hand-sanitizer and figure you've done your duty.
I have some news for you.
There's a new study out on norovirus and the role hand-washing can play in stopping an outbreak.
To sum it up: Wash up!
