And it's actually critically important to get used to things because it's a useful adaptive mechanism to keep track on new events and objects.
而习惯化实际上也是至关重要的,因为这是一种非常有用的适应机制,可以让你注意到新鲜事物。
That shouldn't be too surprising given what we talked about last week, that your immune system, the adaptive immune system in particular, responds to individual antigens differently.
你们不必惊讶,上周我们讲过免疫系统,特别是适应性免疫系统,对不同抗原的应答是具有特异性的
Now these parts of the world are shrinking in the number; but let's say you lived in Ethiopia or Somalia, or places where food really is scarce way too much of the time, then having this particular biological drive, having a brain that wants you to seek out these foods would be highly adaptive.
现在这些地区的数量正在减少,但如果你生活在埃塞俄比亚或是索马里,或是当前食品十分短缺的地区,那么拥有这种生物驱动力,拥有不断驱使你去寻找食物的大脑,会让你有极强的适应能力
