" Humanity is a very old institution. Heredity, cross-breeding have given an irresistible force to bad habits, to vicious reflexes. One person sneezes and gasps because he is passing a rosebush, another breaks out in an eruption at the smell of wet paint, has frequent attacks of colic if he has to start on a journey, and grandchildren of thieves who are themselves millionaires and generous cannot resist the temptation to rob you of fifty francs. "

― Marcel Proust , In Search of Lost Time
