Forget the story about the federal deficit approaching $1 trillion or the story about rats being used to sniff out land mines and TB victims.

Turn instead to the front page of the Metro section, where we learn that many people like to sing along to music in their cars:

With the help of portable players and their favorite music, drivers sing away the stress of their long commutes

This story really has it all - from the links to our caveman past ("A form of whistling our way to work, singing in the car, experts say, is a primal urge rooted in impulses scientists don't fully understand") to the state trooper stating he'd rather people sing along to Mozart than AC/DC to the scientist who explains how singing increases blood levels of a stress-fighting hormone. It's the story that keeps on giving.

Of course, like all Globe "trend" stories, it comes with a disclaimer:

Tom Vanderbilt, author of "Traffic, Why We Drive The Way We Do and What it Says About Us," said he also suspects that more people sing in their cars, although no one has researched this conclusively.
