When new employees come to work at the Boeing production facility in Everett, Washington, one of their first stops is often an exhibition at the company’s Safety Experience Center.

Then, gradually, the tone grows more hopeful. At Boeing, as throughout the aviation industry, disasters led to innovations. Oxygen masks and electronic anti-skid brakes were introduced in the nineteen-sixties, along with bird cannons at airports, to shoo off Canada geese and fellow-fliers.

从生理机制上看，脂肪组织并非单纯的能量储存器官，而会分泌多种激素，其中包括瘦素（leptin）。这一激素在大脑调控生殖轴的过程中发挥着一种“许可”作用：当身体能量储备充足时，大脑更容易启动与生殖发育相关的信号通路。换言之，如果一个机体长期在能量营养丰富的环境中，它也更容易启动青春期。但科学家也观察到，许多出现性早熟的女孩并不肥胖。
