The United States is bracing for a heated political battle after venerable US Supreme Court Justice John Paul Stevens announced his retirement from the bench.
 George Washington University law school professor Jonathan Turley described Stevens's retirement as "an understandably sad moment for liberals."
 Stevens nearly beat the record of his long-serving predecessor  William Douglas  who served for 36 years.
 Born in 1920 in Chicago  Stevens first threw himself into the study of literature in the hope of becoming a professor like his mother.
 But he turned to law after joining the US Navy following the attacks on Pearl Harbor  serving as an intelligence officer from 1942 to 1945.

Study author David Kaufman  director of Boston University's Slone Epidemiology Center   noted that ibuprofen and other NSAIDs are among "the most-used medicines in the U.S.
"[But] most NSAID use is over-the-counter "  he  added  "with users deciding what to take without involvement by health care providers."
 Kaufman  downplayed the notion that users might be popping too many NSAIDs to avoid using addictive opioid painkillers.
"My guess "  he  said  "is that while avoidance of opioids may influence prescribing decisions by doctors  it may not affect consumer behavior very much."
Instead   Kaufman  believes some consumers may simply decide to take an excessive number of pills â regardless of label instructions. But that behavior is "potentially modifiable with better education of users " he added.

As he has been for most of the past year , Bernie Sanders is on the road . 
That , in itself , says something about Sanders and the historical significance of his campaign . 
And although Sanders now seems unlikely to win the Democratic nomination for President , he has achieved much more than that . 
It is obvious that Sanders has , in the process , put a scare into Hillary Clinton 's campaign . 
Of the twenty-five states that have held Democratic primaries and caucuses , Sanders has won nine and Clinton has won sixteen -LRB- plus American Samoa and the Northern Mariana Islands -RRB- . 
But outside the South , where Clinton has won large majorities of black voters , many of Sanders 's losses have been narrow . 
Given the way the primary calendar was structured , with many Southern states voting in February and March , Sanders 's route to victory was always going to be precarious . 
The Sanders campaign achieved its initial goal , virtually tying Clinton in Iowa , trouncing her in New Hampshire , and losing by a whisker in Nevada . 
Had Sanders earned a few thousand more votes in Iowa and Nevada , he would have won all three contests . 
Still , Sanders carried Colorado , Minnesota , Oklahoma , and Vermont , and in Massachusetts he came within two percentage points of victory . 
Had Sanders followed up that shocking triumph by carrying Illinois , Missouri , and Ohio , this past Tuesday , his insurgent game plan would have been back on track . 
That it did n't quite work out does n't detract from the impact Sanders has had . 
On issues like inequality , trade , the environment , corporate offshoring , and bringing Wall Street miscreants to justice , the former Secretary of State has adopted Sanders 's language -- and , in some cases , his policies . 
Clinton had undoubtedly always intended to run as a center-left progressive in 2016 , just as she did in 2008 , but Sanders has forced her onto ground she had n't originally intended to occupy . 
Even Republicans have been taking up some of Sanders 's themes . 
Of course , the regressive tax policies that Cruz , Trump , and Kasich are advocating would exacerbate inequality , rather than reduce it , but the fact that Republicans have felt obliged to address these issues at all surely owes something to Sanders and the populist wave that he represents . 
Sanders 's other big theme is money in politics . 
But nobody has made the argument as passionately or as powerfully as Sanders . 
Since Sanders uttered these words , last May , his message has n't changed . 
In much the same way that Trump has labelled Sanders a Communist , the Republicans of Bryan 's day called him a fanatic who would wreck the American economy . 
It 's too early to say what Sanders 's legacy will be , or whether some of the ideas that he is pushing -- such as breaking up the big banks , introducing a single-payer health-care system , and returning tax rates on the rich closer to the levels that F.D.R. introduced -- will eventually be adopted . 
But it is also evident that , in the past ten months , Sanders has defied the pundits , alarmed the comfortable , and inspired the young .
