Over millions of years of human, and prior pre-human, evolution, some things became so important that that they’re not optional, they’re built into human DNA. They’re reflexes, things that happen involuntarily, without any conscious thought beforehand. Breathing is a good example. People breathe all day every day without thinking about it. In fact, you have to consciously make the decision to stop breathing. Oxygenating blood is so important that breathing is not optional.
Protecting your eyes is another important built-in function. When something comes toward your eyes, you blink without thinking about it. It is so important that your eyes not contact other objects that your eyelids close immediately. You have no choice.
Who am I to argue with millions of years of evolution?
