Imagine life without ageing. You could live for hundreds of years with the mental and physical attributes of your 25-year-old self. Would you be tempted?

How should we make sense of Nigeria's 21st Century identity? Newly anointed as Africa's number one economy, it is an oil-rich emerging power.

Hardtalk speaks to the highly acclaimed Nigerian novelist, Chimamanda Ngozi Adichie. Her fiction explores her country's troubled past and current challenges.

Dr Kizza Besigye is a former ally of Uganda’s President Museveni who has become his biggest critic and the country’s best known opposition figure. As the former leader of the main opposition party – the Forum for Democratic Change – he has run three times against President Museveni in elections and lost each time. He has called for popular protests in Uganda like the ones that lead to the uprisings of the Arab Spring. So why has he failed to mobilise public opinion behind him?
