ALL THAT WE PERCEIVE

It proved that the second hypothesis—that we do perceive everything all the time but the brain categorizes distractions differently—wasn't true either.

它证明了第二个假设——我们确实一直感知着所有事，但大脑对干扰的分类不同——也不是真实的。

In fact, we could go further and say that were not alive as all life reacts to its environment, by definition, and to react you must therefore be able to perceive.

事实上，我们能进一步说，他们已经不在人世，因为从定义上讲，一切生命都会对周围环境做出反应。而要做出反应就必须能够感知。

It turns out that people differ in how they perceive many if not all odors, and most of us have at least one scent we cannot detect at all.

结果证明，无法辨别全部气味的人，对气味的感知方法也不同，而且每个人至少有一种压根无法感知的气味。
