PROBLEM: 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.

PROBLEM: Rihanna  has emerged as the unlikely inspiration behind Arsenal's thumping 5-1 win against Everton.
 The singer  was at the Emirates to watch the match and enjoy the Gunner's work  work  work  work  work ethic.
After the match   she  posed with midfielder  Mesut Ozil  who described  her  as the team's "lucky charm".
The German said he was "still unbeaten with Riri" - a reference to when  she  came to watch the 2014 World Cup Final between Germany and Argentina.
Ozil himself couldn't get on the scoresheet but with  Rihanna  pulling the inspirational strings during a pre-match meet and greet  other players stepped up.
It's just a shame that whoever was looking after  her  social accounts still referred to the game as "soccer".
After the game  manager Arsene Wenger seemed to play down the importance of  Rihanna 's contribution  focusing instead on his side's "penetration and sharper game".
Given Arsenal's up and down season  there are probably high level talks with  Rihanna 's people to see if  her  schedule allows any more trips to watch the team - with one eye surely on  their  next Europa League match  away at Ostersunds FK.

SOLUTION: Rihanna

Asked about the timing of the budget process and the measure now in place to fund government operations through early December at last yearâs levels   Ryan  told a news conference  âWe might need a little bit more time to give the appropriators time to write their billâ for fiscal 2018 spending that would extend through next Sept. 30.
 Ryan  said a temporary spending bill  if needed while the longer-term one is being negotiated  would extend for a short time. âWe are not talking about going into next year â  he  said.
