It’s not a chocolate coin wrapped in gold foil, people. That’s actual metal that composes that Olympic medal, so why do athletes bite them?

大伙儿，这可不是包裹在金箔纸里的金币巧克力，奥运会金牌是货真价实的金属制品，那为什么运动员热衷于咬金牌?

There’s actually a few reasons, but the most obvious is that it’s a pose photographers really, really like to capture.

还真有几种解释，但最明显的一个原因是，这是一个摄影师非常喜欢捕捉的拍照造型。

“It’s become an obsession with the photographers,” David Wallechinsky, the president of the International Society of Olympic Historians and co-author of “The Complete Book of the Olympics” told CNN in 2012. “I think they look at it as an iconic shot, as something that you can probably sell. I don’t think it’s something the athletes would probably do on their own.”

国际奥林匹克历史学家协会主席、《奥运大全》的合著者戴维•沃利金斯基在2012年接受CNN采访时说：“这已成为摄影师痴迷的拍照造型，我觉得他们把这看作一种标志性的镜头，认为这样的照片会比较受欢迎。不过如果让运动员自己选的话，我觉得他们还真不一定会这么做。”

Biting down on a hunk of metal is more likely something someone might have done during the Gold Rush to test whether the shiny golden rock they just panned for was actually pyrite or fool’s gold. Human teeth are harder than gold but softer than pyrite, according to the Mohs Hardness Scale. This means a quick gnaw to real gold would actually leave an indentation. A hard chew of pyrite, meanwhile, might damage your teeth.
