A man should not marry after thirty years of age; should not enter the government service after the age of forty; should not have any more children after the age of fifty; and should not travel after the age of sixty. This is because the proper time for those things has passed. At sunrise the country is bright and fresh, and you dress, wash, and eat your breakfast, but before long it is noon. Then you realize how quickly time passes. I am always surprised when people talk about other people's ages, because what is a lifetime but a small part of much greater period? Why talk about insects when the whole world is before you? How can you count time by years? All that is clear is that time passes, and all the time there is a continual change going on. Some change has taken place ever since I began to write this. This continual change and decay fills me with sadness.
