A passenger, sterilized in body and mind (lest he bring into our great land either Asian flu or Asian ideas), pumped full of vitamins and videotapes, will be able to move from city to city, from continent to continent, from planet to planet––with ever-increasing speed and security. And the vision of all this phenomenally efficient, solicitous machinery is supposed to take our breath away, so that we never get around to asking what exactly is gained by these lightening-fast peregrinations. Such speeds used to be too much for our old, animal body; travel from hemisphere to hemisphere, when too sudden, would disrupt its circadian rythmn. But, fortunately, a drug has been found to nullify that disruption. True, the drug sometimes causes depression, but there are other drugs to raise your spirits. They do cause heart disease. But, then, one can insert polyethylene tubes into the coronary arteries to prevent them from clogging.
