After the jump, a series of American PSAs warning about Swine Flu, dating from 1976. The second of them features a soundtrack that sounds as though it more properly should accompany a detective show on American TV. Or, for that matter, a movie such as The Three Days of the Condor. Appropriate in times such as these, the government never ceases to remind us, when You Can Never Be Too Careful. Trust Nobody, remember.
These days, mind you, any such government-sponsored warning would be much, much more terrifying and, one presumes, be designed to convince us all that the apocalypse was upon us and yet also - conveniently - avertable.
