You know it because countless magazines have screamed it at you from the checkout line. Because the gym you walk past every morning is waiving its initiation fee. The holidays are over. It's time to get in shape. So pull on your gym shorts and tighten the laces on your running shoes.

Oh yeah, and don't forget your headphones. You're going to need some motivation, and nothing gets the job done like music. Need proof? We just happen to have some, courtesy of neuroscientist Robert Zatorre, who spoke with Morning Edition's Linda Wertheimer.

In 2008, Richard Bennett had been out of the Marines for nearly three years after being injured in Iraq. That's when he caught the attention of Craig Williams, who was looking for a partner to help expand his successful construction business in Norristown, Pa.

"I had developed a pretty solid construction company, and I wanted a partner," says Williams, 44. "As an African-American businessman, I wanted a young African-American soldier coming home. It seemed like a great opportunity to provide an opportunity."

"This is a valid appointment," he told NPR's Robert Siegel. "But, again, I'm not going to be distracted by the details of that. My job is to be the director of this consumer bureau, to look out for consumers across the country and I'm going to focus 100 percent on that job."

Robert asked if he was just going to "ignore whatever litigation might develop from that" and Cordray said, "that's correct."

Rick Santorum has been upsetting elections from the beginning.

He was only 32 years old when he toppled a seven-term incumbent in a majority Democratic district in western Pennsylvania.

Just four years later, Santorum rode the Republican wave of 1994 into the Senate representing Pennsylvania. And from the beginning, Santorum has stood for unwavering social conservatism, especially on the issue of abortion.

"Give the baby a chance to live," said Santorum while delivering a speech on the Senate floor in 1997.

A scandal involving French-made breast implants continues to widen.

The implants contain industrial-grade silicone that cause abnormally high rupture rates, according to critics. They have been sold in many countries in Europe and beyond, though not in the United States. Now, the French government has opened a criminal investigation into the company.

French television showed footage on Thursday of investigators and a judge searching the factory of the Poly Implant Prothese company, or PIP, in southern France.
