No work of literature, and no doctor, had prepared the former residents of Katalin Street for the fierce light that old age would bring to bear on the shadowy, barely sensed corridor down which they had walked in the earlier decades of their lives, or the way it would rearrange their memories and system of values. They knew they should expect certain biological changes: that the body would set about its work of demolition with the same meticulous attention to detail that from the moment of conception it had applied to the task of preparing itself for the journey ahead. They had accepted that there would be alterations in their appearance and a weakening of the senses, along with changes in their tastes, their habits, and their needs; that they might fall prey to gluttony or lose all interest in food, become fear-ridden or hypersensitive or fractious. They had resigned themselves to the prospect of increasing difficulties with digestion and sleeping, things they had taken for granted when young, like life itself. But no one had told them that the most frightening thing of all about the loss of youth is not what is taken away but what is granted in exchange. Not wisdom. Not serenity. Not sound judgment or tranquility. Only the awareness of universal disintegration.
