Chapter 66 watch the dust fly

On the African continent, tsetse flies never bite zebras. Once bitten by tsetse flies, they may suffer from "sleeping sickness"-fever, pain, nervous disorders, and even death.Scientists have discovered after research that the vision of tsetse flies is very special, and they are generally only attracted by large areas of uniform color, while zebras have black and white stripes, which are often ignored by tsetse flies. However, the contrasting stripes on the zebra make it vulnerable to predators such as lions, which means that the selection of zebras in the evolutionary process makes it more likely to be eaten by lions, of course , it also successfully avoided the trouble of sleeping sickness.There is no perfect choice in this world, and there are very few things that kill two birds with one stone. However, we must face many choices. This is life.

Just like the familiar and unfamiliar dust, it pollutes the air, but it also renders our sky bluer.We all have the experience that when the sun shines into the room, there will be many fine dust flying around. It is these small dust that reflect and scatter the sunlight, making the sunlight soft and comfortable.Dust also has the function of filtering light. It filters out the red, orange, yellow, green and other strong colors of light from the sun, leaving weaker blue light, which is absorbed, reflected and scattered by the dust in the atmosphere, so , the sky became blue and gentle. Existence is reasonable, and the sky contains dust, which turns out to be beautiful wisdom, not just because of a broad mind.There is no once-and-for-all choice in life, but there is nothing useless in this world, so when we face choices, we can be a little more calm, and when we face everything, we can be more tolerant.
