Mostly Harmless: Three Douglas Adams Inventions We Wish Were Real
Peril Sensitive Sunglasses
Listen, the Universe is a dangerous place, full of threats ranging from Vogon poetry to the Ravenous Bugblatter Beast of Traal. If you’re a hoopy frood who knows where your towel is, you might even survive out there, if you’re lucky. But just as the sight of the approaching ground might interfere with achieving flight, the vision of your imminent doom is likely to pose a serious distraction, siphoning away energy and mental faculties required to avoid said doom. Well, as long as you’ve got yourself a set of Joo Janta 200 Super-Chromatic Peril Sensitive Sunglasses, you’ll be just fine. They’re designed to help the wearer “develop a relaxed attitude to danger,” specifically by turning completely opaque at the first sign of danger, thus ensuring that you don’t see anything upsetting, like the Vogon constructor fleet that’s about to vaporize your homeworld or the vengeful, perpetually reincarnating creature that you’ve killed thousands of times over without realizing it.
It occurs to me that mastering flight might be made quite a bit easier if you incorporate a set of the Peril Sensitive Sunglasses. If nothing else, the time leading up to your abrupt deceleration might be a bit less stressful.
