The sun is as miraculous as life itself. In fact, the miracle of life depends on the miracle of the sun. But the sun is so powerful that we only need a little sunshine. Too much sunshine causes blindness, skin cancer, and even death. This is particularly true for pale-skinned people who don't tan easily. It is important to protect ourselves from excess sunshine by avoiding the midday sun and by wearing a hat, sunglasses, and appropriate clothing. We must regulate the amount of sunshine in our lives, so that we get enough, but not too much.
