A monthly series in which broadcaster and acclaimed historical novelist Sarah Dunant delves into the past to help frame the present, bringing to life worlds that span the centuries. Taking modern day anxieties as its starting point, the programme considers how certain questions are constant, yet also change their shape over time.

This month, Sarah delves into history to find some answers to the age old question of old age. At a time when lengthening life-expectancy brings increasing pressure on our modern society and the older generation searches for a place within it, she looks at the different responses down the years to this most human of constants.

From the elder statesman of Republican Rome still striving for relevance to the story of how the discovery of Alzheimer's transformed modern America's attitude to growing old, When Greeks Flew Kites takes an honest look at the history of old age and some of the surprising lessons it can teach us today.

The guests are Professor Lyndal Roper from Oxford University, Professor Susannah Ottaway from Carleton College, Professor Jesse Ballenger from Drexel University, and Professor Mary Harlow from the University of Leicester.
