Peter France concludes his examination of people's experiences of being alone, either through choice or circumstances beyond their control. Isolation. This week he explores the problems and insights of forced solitude. From the harrowing tale of an anti-apartheid prisoner to the lonely old lady down the road, loneliness can bring pain and despair. But forced solitude can also bring insight, a time to reflect and a deeper understanding of ourselves.
