Occupy Wall Street protesters are flocking to nearby health clinics for testing for sexually-transmitted diseases, including HIV, after getting their freak on in 1960s-style hookups with crusty strangers, sources said. "Last week was free love," a medical professional at a nearby clinic said, referring to the number of people who organizers referred for STD testing. A volunteer at Zuccotti Park admitted concern among protesters about STDs. "We give directions to clinics if people ask for information regarding STDs," the volunteer, who identified himself only as "Captain," said, adding that pregnancy tests are also a hot item.
