KJN: What do you mean by “sing while you may”?

EK: “Sing while you may” is basically my optimism ... in action. I mean, this is a very special time for the planet. We’re witnessing things speed up incredibly, rapidly. Um ... it can be that we are literally on the verge of the end of the world as we know it — I doubt that, if I’m honest. What I do know is that this is an extremely exciting and sometimes scary period of time to live in, and I say enjoy it — cherish it — be glad you live now  — sing while you may. It may not be very long, but then again it may be for ages, you know.
