He did live a long life... and his deeds had an impact on those who will continue after his final memorial services.
RIP During my lifetime I have dedicated myself to this struggle of the African people. I have fought against white domination, and I have fought against black domination. I have cherished the ideal of a democratic and free society in which all persons live together in harmony and with equal opportunities. It is an ideal which I hope to live for and to achieve. But if needs be, it is an ideal for which I am prepared to die. -Nelson Mandella Nelson Mandela Quotes - WSJ.com
You have so few heros, you hate to lose one. (no one is perfect, some manage to do great deeds in spite of not being perfect)
