These people thought of everything. Pauker wondered how many tons of food-stuffs they saved having to haul just by this one device.

"A single unfortunate effect was found from this close temperature control, however. Space-medical records revealed that if the body is permitted to adjust to a single temperature over too long a period, the body mechanism for its own heat-control becomes, you might say, rusty. That is, when the passenger passes from the ship into the varying temperatures of normal living, his body has difficulty taking over the job of thermal control again.

"Excessive respiratory ailments such as flu, colds and pneumonia, prompted the use of our present system. Since it was deemed necessary to keep the body thermal adjustment equipment functioning, each passenger now receives a minute injection of a retardation drug that has the desired effect. This drug creates a slight lag between the time of heat sensation and the beginning of perspiration.

"The body is allowed to sense an accumulation of heat, which finally triggers the sweat glands into producing a slight oversupply of skin moisture. The moving, dry air then evaporates this perspiration which continues to flow a brief period after optimum sensation is reached. Thus, the body begins to experience the first sensation of chill—even though the temperature of the air remains at 98.6 degrees. At this point, the reaction lag expires and the perspiration stops, the body is warmed as if bathed in hotter air again.

"This gentle oscillation between sensations of warmth and coolness has a very pleasant secondary effect, you will find. The varying temperature of your skin is too slight to be dangerous, yet it breaks the tactile monotony which nine months of unchanging climate would bring."

Pauker's teeth chattered together as the chill swept over him. This is all very goddamned neat when it works, he thought miserably, but how do you turn off the sweat?
