Health and Society

• Americans are dying of heart disease and strokes at a rising rate in middle age. Normally that period is considered the prime of life.
  
  But an analysis of mortality statistics by the WSJ shows the problem is geographically widespread.
  
  Death rates from cardiovascular disease among people between the ages of 45 and 64 are rising in cities all across the U.S., including in some of the most unlikely places. The findings suggest that the underlying causes of cardiovascular disease are universal and difficult to address.

• Only one known copy of the footage of Super Bowl I in 1967 exists. The copy is owned by Troy Haupt, a 50-year-old nurse anesthetist in North Carolina.
  
  Haupt found two reels of bulky two-inch videotape in his mother’s attic, but it remains unseen by the public because of a legal standoff between him and the NFL.
  
  Now, with Haupt’s blessing, two filmmakers want to change that—and they say they will take the NFL to court to make it happen.
  
  The filmmakers say if they raise $1.5 million, they will complete a documentary on the legal fight, and stream the game online for free.

Business and Economics

• The U.S. and China signed a trade deal, calling a cease-fire in a two-year trade war. Officials said the eight-part agreement will lead to an increase in sales of U.S. goods and services to China, further open Chinese markets to foreign firms—especially in financial services—and provide strong new protections for trade secrets and intellectual property.

Government and Politics

• The Senate opened the impeachment trial of President Trump.
  
  Chief Justice John Roberts swore in the senators, who pledged to deliver impartial justice and heard the reading of the charges of abuse of power and obstruction of Congress.
  
  Disputes over which witnesses and evidence will be allowed aren’t expected to be decided until after the trial begins in earnest Tuesday.
