Here's a fine old FDA public service announcement in which Raymond Massey gravely warns America to steer clear of bizarro quack devices that claim to treat arthritis with z-rays or cure cancer with music.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
