I have enjoyed greatly the second blooming that comes when you finish the life of the emotions and of personal relations; and suddenly find - at the age of fifty, say - that a whole new life has opened before you, filled with things you can think about, study, or read about...It is as if a fresh sap of ideas and thoughts was rising in you. ~ Agatha Christie
