Have you ever noticed that while it's pretty easy to tell your dog is sick,it's much harder to know how your cat or bird are feeling?
你有没有注意到,自家狗生病很容易就被你发现,但很难知晓你的猫或鸟是何感觉?
Well, before you start asking your dog why it can't be more stoic like animals half its size, it's probably worth considering each animal's place in the food chain.
好吧,在开始前问问你的狗为什么不能像身材不及一半大小的动物们更强韧,这可能要考虑每种动物处在食物链当中的位置。
You see, the lower down the food chain you are, the more important it is for you to hide any sign of illness.
你看,你越是处于食物链下层,隐藏任何疾病的迹象就显得越发重要。
Obvious illness or pain function as red flags for predators.
明显的疾病或疼痛表象就是对捕食者们举起了白旗。
You may as well wear a sign saying, “Easy meal, guys. Come and get me.”
你就仿佛穿着标志，上面写道:“伙计们，我是顿白来的大餐。过来抓我吧。”
