And the good thing about perceiving ultraviolet is that you can hear if it's a good day or a bad day to sunbathe, because ultraviolet is a dangerous color, a color that can actually kill us, so I think we should all have this wish to perceive things that we cannot perceive.
感应紫外线的好处则是， 你能听到说今天的天气适不适合晒日光浴， 因为紫外线还是比较危险的， 它能够使人类致死的。因此我觉得人们应该想要去 感知那些我们无法感知的东西。
