But the severity of his disease continued to make him prone to seizures and life-threatening infections. He never finished his senior year of high school because of health complications, and failing eyesight forced him to stop working at McDonald's after 1981. He has never since been strong enough to hold...
...poorest people in the world. He'd visualized peasant farmers wading into paddies to set out the tender seedlings and winnowing the grain at harvest time in handwoven baskets.

Such micro-air vehicles will fly as far as six miles from their takeoff point for as long as two hours, feeding video images back to special military ground stations that will use the information to coordinate ground attacks and air strikes. Pentagon researchers are busy developing aviation assets even tinier than such mechanical sparrows. They're training honeybees, parasitic wasps and giant sphinx moths...
