By some estimates, we Americans throw away about 40 percent of our food, from the cabbage that's wilting in our refrigerators, to the fruit that's falling off the orange tree in our neighbor's backyard.
When it comes to the Olympics, politics intrudes more often than not.
President Obama has decided not to attend the Winter Olympics in Sochi, Russia, in February. The official U.S. delegation will not include a president, vice president, first lady or former president for the first time since 2000.
Instead, Obama asked athletes including openly gay tennis great Billie Jean King and two-time hockey medalist Caitlin Cahow to represent the country. American gay-rights groups, angered by an anti-gay law Russia enacted in June, applauded the move.
