Reliance on cars harm our health in a number of ways, Boston University economist Austin Frakt said.

Be smart: On top of removing you from the horrors of traffic, walking and riding a bike offer the benefits of at least light exercise.

The brutal commute:

  • Exposure to the pollution caused by exhaust can cause respiratory problems.
  • Researchers have found that people who spend more time in the car had worse health and were more likely to be depressed.
  • We spend about 40 hours per year sitting in traffic, and unanticipated delays on top of the gridlock we’re used to are a cause of stress, which we know to have a host of health effects. One study linked “extreme traffic” to higher rates of domestic violence.

Sen. Bernie Sanders wanted to keep his momentum after winning contests in New Hampshire and Nevada, while former Vice President Joe Biden hoped to keep his own campaign alive. The other five candidates were just trying to hang on.

What's happening: Seven contenders for the Democratic presidential nomination were in Charleston, South Carolina, for the tenth debate, just days before the South Carolina primary and a week before Super Tuesday. They spoke, sometimes over each other, about health care, Russian interference in the election, foreign policy the economy, gun control, marijuana, education, and race.

The 10th Democratic debate was billed as the most consequential of the primary thus far, but Tuesday night's high-stakes affair was at times awkward and unfocused as moderators struggled to rein in candidates desperate to make one last splash before Saturday's primary in South Carolina and Super Tuesday.

The big picture: After cementing himself as the Democratic favorite with a sweeping win in Nevada, Sen. Bernie Sanders came under fire as the front-runner for the first time on the debate stage. Former New York Mayor Michael Bloomberg, who will be on the ballot for the first time next Tuesday, was a progressive foil once again, but he appeared more prepared after taking a drubbing at the Nevada debate.
