Old Age a Very Short Introduction

The three centuries which followed the conquests of Alexander are perhaps the most thrilling of all periods of ancient history. This was an age of cultural globalization: in the third century BC, a single language carried you from the Rhone to the Indus. A Celt from the lower Danube could serve in the mercenary army of a Macedonian king ruling in Egypt, and a Greek philosopher from Cyprus could compare the religions of the Brahmins and the Jews on the basis of first-hand knowledge of both. Kings from Sicily to Tajikistan struggled to meet the challenges of ruling multi-ethnic states, and Greek city-states came together under the earliest federal governments known to history. The scientists of Ptolemaic Alexandria measured the circumference of the earth, while pioneering Greek Argonauts explored the Indian Ocean and the Atlantic coast of Africa.

The French Revolution is a time of history made familiar from Dickens, Baroness Orczy, and Tolstoy, as well as the legends of let them eat cake, and tricolours. Beginning in 1789, this period of extreme political and social unrest saw the end of the French monarchy, the death of an extraordinary number of people beneath the guillotine's blade during the Terror, and the rise of Napoleon, as well as far reaching consequences still with us today, such as the enduring ideology of human rights, and decimalization.

As more of us live longer, the fear of an old age devastated by brain diseases like dementia is growing. Many people are already facing the challenges posed by these progressive and terminal conditions, whether in person or because they are caring for loved ones. Dementia is now the fifth most common cause of death across the world. It is a small wonder that understanding, preventing, and finally curing these illnesses is now a global priority.
