“Encarada do ponto de vista da juventude, a vida parece um futuro
indefinidamente longo, ao passo que, na velhice, ela parece um passado
deveras curto. Assim, a vida no seu início se apresenta do mesmo modo
que as coisas quando as olhamos através de um binóculo usado ao contrário;
mas, ao
seu final, ela se parece com as coisas  tal qual são vistas quando o
binóculo
é usado de modo normal. Um homem precisa ter envelhecido e vivido
bastante para perceber como a vida é curta”.
