Former Vice President Dick Cheney is recovering from a heart transplant he received Saturday at Inova Fairfax Hospital in Falls Church, Va.

The operation makes Cheney among more than 2,300 Americans who get heart transplants every year.

Heart transplantation has come a long way since Christiaan Barnard stitched the heart of a young woman into the chest of a middle-aged man in South Africa in 1967. That transplant recipient died 18 days later. Today, recipients can expect to get a decade or more of life from their new hearts.

It's the hottest ticket in Washington, D.C. Even the flossiest lawyers in town can't get a seat. Senators, congressmen, Cabinet and White House officials are all vying for a place.

At the U.S. Supreme Court, people have been lining up for days, waiting to hear this week's historic oral arguments on President Obama's health care law. The arguments will last for six hours over a three-day period, the longest argument in more than 40 years.

When the U.S. Supreme Court hears challenges to the Obama administration's health care law this week, the arguments will be complex, with questions about states' rights, mandatory insurance, and Medicaid.

To introduce those concepts — and to give the rest of us something to do while the court hears six hours of arguments — we offer a word search game. The grid below features many words you'll likely hear this week, as NPR's Nina Totenberg reports from the court.
