Reader challenge: Can you explain duration better than The New York Times?

The duration of a bond isn’t easy to explain in few words. This is why I was delighted by the brief description I found in The New York Times.

Author Carla Fried wrote, “For the most part, managers seem to agree that it is best to limit a fund’s duration, or sensitivity to changes in interest rates. The longer the duration, the more yield you get today, but with the trade-off of a bigger price decline if rates rise.” This paragraph appeared in “Tiny Yields Pose Risks for Bond Funds” on July 8, 2012.

Can YOU explain duration better?

I’m interested in alternative explanations of duration that an ordinary American can understand. Please leave your suggestions below.
