There is no reason for you to think anyone has lived long just because he has grey hairs or wrinkles. He has not lived long; he has existed long. For suppose you should imagine that a man had a great voyage when in fact he was caught by a fierce storm as soon as he left harbor, was swept this way and that by strong winds from different directions, and was driven along the same path in circles. He did not make a great voyage. He was greatly tossed about. Seneca, On the Shortness of Life 7.10
