From Michele Hanson in the Guardian, we get this:

Last Saturday was the 50th anniversary of the launch of the Campaign for Nuclear Disarmament, so I went to a party to celebrate its birthday in City Hall with my friend Miriam, a lifelong member. My membership has lapsed and I haven't thought much about CND for decades, having put it out of my mind soon after the Cuban missile crisis, because I was too scared to think about nuclear holocaust any more and had been spending rather too much time weeping with fright.
