Ender's Shadow

mouth. He glanced at Dimak. Dimak did not crack a smile or show any understanding of what the trainer was thinking.
      "Is the heartrate monitor in our clothing? If we take off any part of our clothes while we're exercising, does it --”
      "You are not authorized to be out of uniform in the gym," said the trainer. "The room is kept cold on purpose so that you will not need to remove clothing. You will be monitored at all times.”
      Not really an answer, but it told him what he needed to know. The monitoring depended on the clothes. Maybe there was an identifier in the clothing and by palming in, they told the gym sensors which kid was wearing which set of clothing. That would make sense.
      So clothing was probably anonymous from the time you put on a clean set until you palmed in somewhere. That was important -- it meant that it might be possible to be untagged without being naked. Naked, Bean figured, would probably be conspicuous around here.
      They all exercised and the trainer told them which of them were not up to the right heartrate and which of them were pushing too hard and would fatigue themselves too soon. Bean quickly got an idea of the level he had to work at, and then forgot about it. He'd remember by reflex, now that he knew.
      It was mealtime, then. They were alone in the mess hall -- as fresh arrivals, they were on a separate schedule that day. The food was good and there was a lot of it. Bean was stunned when some of the kids looked at their portion and complained about how little there was. It was a feast! Bean couldn't finish it. The whiners were informed by the cooks that the quantities were all adapted to their individual dietary needs -- each kid's portion size came up on a computer display when he palmed in upon entering the mess hall.
      So you don't eat without your palm on a pad. Important to know.
      Bean soon found out that his size was going to get official attention. When he brought his half-finished tray to the disposal unit, an electronic chiming sound brought the on-duty nutritionist to speak to him. "It's your first day, so we aren't going to be rigid about it. But your portions are scientifically calibrated to meet your dietary needs, and in the future you will finish every bit of what you are served.”
      Bean looked at him without a word. He had already made his decision. If his exercise program made him hungrier, then he'd eat more. But if they were expecting him to gorge himself, they could forget it. It would be a simple enough matter to dump excess food onto the trays of the whiners. They'd be happy with it, and Bean would eat only as much as his body wanted. He remembered hunger very well, but he had lived with Sister Carlotta for many months, and he knew to trust his own appetite. For a while he had let her goad him into eating more than he actually was hungry for. The result had been a sense of loginess, a harder time sleeping and a harder time staying awake. He went back to eating only as much as his body wanted, letting his hunger be his guide, and it kept him sharp and quick. That was the only nutritionist he trusted. Let the whiners get sluggish.
      Dimak stood after several of them had finished eating. "When you're through, go back to the barracks. If you think you can find it. If you have any doubt, wait for me and I'll bring the last group back myself.”
      The corridors were empty when Bean went out into the corridor. The other kids palmed the wall and their green-brown-green strip turned on. Bean watched them go. One of them turned back. "Aren't you coming?" Bean said nothing. There was nothing to say. He was obviously standing still. It was a stupid question. The kid turned around and jogged on down the corridor toward the barracks.
      Bean went the other way. No stripes on the wall. He knew that there was no better time to explore than now. If he was caught out of the area he was supposed to be in, they'd believe him if he claimed to have got lost.
      The corridor sloped up both behind him and in front of him. To his eyes it looked like he was always going uphill, and when he looked back, it was uphill to go back the way he had come. Strange. But Dimak had already explained that the station was a huge wheel, spinning in space so that centrifugal force would replace gravity. That meant the main corridor on each level was a big circle, so you'd always come back to where you started, and "down" was always toward the outside of the circle. Bean
