He reflexively snapped his biosensor bracelet back on and waited for the gray surface to change to green. He didn't like the idea of the bracelet at first, but he'd come to accept it as a necessary part of life now. They all had. He didn't even register the faint prick of the sampling needles. They were so small, he had trouble finding them in the housing when had taken one apart. He probably wouldn't have if he hadn't inadvertently laid out the pieces on some black cloth that Ruby was using to make him a suit for her sister's wedding. Clothing from Mexico and China was so cheap nowadays that he thought it was quaint that she made so many of their clothes. Nevertheless, she was unhappy to find a bracelet disassembled on that cloth on her table. He was fascinated by how things worked and frequently wrecked them to find out. Reassembly is always much harder. The sensor chip in the bracelet was truly amazing. On a chip one centimeter square were thousands of DNA or RNA sequences of as many diseases, mostly infectious, a few cancerous. The bracelet sampled body fluid from the skin on the wrist at intervals set by the wearer. John's and the kids' bracelets sampled twice an hour. He had tried to get Ruby to do the same, but she hated the whole idea. She had compromised and agreed to sample once a day, in the middle of the night. He often found himself laying awake at 3AM, and more than once had not been able to help himself from watching as her bracelet tested her. There was no way he could even think about going to back to sleep until it glowed green.
