Sex goes visual
　　Pheromones, like other scents, hitch a ride through the air on other particles, such as water droplets. They generally hover just 10 inches off the ground, however. So odds are slim they'll waft up to a human nose and fuel sudden passion at a nightclub.
　　Watch any construction worker whistling at a passing woman from half a block away, and you can see how visual cues can be more powerful.　
　　視覺吸引
　　信息素就和其他味道一樣，需要通過通過空氣中的其他微粒進行傳播，比如水蒸氣。不過它們只在距地面10英寸左右的地方存在。所以但夜總會里，這些氣味能夠進入鼻子里、并馬上點著激情的機會并不大。
　相反的，如果你見過建筑工人們在女人從老遠走過來就大吹口哨的話，你就明白視覺的信息是多么強大。
