On the Ides of March, a friend sent me an image of a knife in a bottle of Caesar salad dressing. By coincidence, I also heard that the Senate took a knife to partisan bickering, science denial, and clock-switching in one fell swoop. A bill that would establish permanent Daylight Saving Time (DST) passed unanimously and without debate.The bill polls well. Its sponsors insist they are on the side of "strong science," claiming the time change leads to higher rates of "heart attacks, car accidents and pedestrian accidents."
