I've always loved the theme of the Reverend John Donne's poem 'No Man Is an Island' about the interconnectness of all human beings on earth - every person's death affects me because I'm part of humankind.
I feel John Donne's message is even more relevant now than when it was published in 1624 as we live in a 'Global Village' and news, positive and negative travels around the globe in a fraction of a second.
