Scarlett Johansson made it a point to let reporters know that while she doesn't consider herself promiscuous, she makes sure that she gets tested for HIV twice a year. She says that this is just part of being a decent human being.
Uhm, Scarlett. I'm pretty sure that if you're not promiscuous, you don't really stand much chance of picking up HIV. I could be wrong, but I think that you have to be sexually active to pick up an STD.
