Why Africa has old leaders and young people

The recent election victory of Uganda's President Yoweri Museveni has once again raised questions about term limits and democracy in some African countries.

However, the Ugandan leader, who is entering his fifth term in office, is not the only one.

The issue of presidential terms has caused public protests in Burundi, Democratic Republic of Congo and in 2014 led to the ousting of Blaise Compaore, long-time leader of Burkina Faso.

BBC Africa Business Report's Matthew Davies looks at the contrast between Africa's old leaders and its young population.
