Nelson Mandela’s death, at the age of 95, comes as a relief. He should have been allowed the dignity of only dying once. In the past two years, in and out of hospital, he seldom recognised his wife Graça Machel, his former wife Winnie, his children or his old comrades from the ANC. What is more, since the end of his presidency in 1999, the 'rainbow nation' had been dying with him.
