Edge Magazine's Annual Question looks pretty interesting, although I've only read a couple of the 151 responses from leading thinkers yet.
We worry because we are built to anticipate the future. Nothing can stop us from worrying, but science can teach us how to worry better, and when to stop worrying.
WHAT SHOULD WE BE WORRIED ABOUT?
Tell us something that worries you (for scientific reasons), but doesn't seem to be on the popular radar yet—and why it should be. Or tell us something that you have stopped worrying about, even if others do, and why it should be taken off the radar.
