Question: 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.

Answer: David Kaufman

 Jamie Wall  and  his  brothers were volunteer firefighters in Gillsburg  Miss.  a small town about 8 miles southwest of the crash site.
 Wall  said after hearing about the crash   he  set out to the site using the spotlight of a Coast Guard helicopter to guide  him .
 He  brought two tools: a flashlight and a hatchet.
In  his  survey of the scene   Wall  said  he  was literally on top of some of the crash victims.
"I found someone on the ground alive "  he  said. "When I walked to the other side of the plane  I tripped on another person."
"I took out this hatchet  " Wall  said as  he  pulled out a rusted hatchet from a sheath on  his  hip. "I heard some screaming.  He  (Mark Howard) was pinned in a hole of the plane. I chopped  him  out."
The scene  with mangled bodies and cries for help  was overwhelming   Wall  said.
"I got down and prayed  " Wall  said   his  voice shaking. "I said  'I need help  God  to deal with this.'"
"When I got there  everyone was covered in blood "  he  said.
Everybody helped   Wall  explained to Howard at the crash site.
"It was people that didn't come to the site at all  " Wall  said.
"Some of them were out on that highway directing traffic. Some of them went home and got tractors. My wife was home on a CB radio. I'm relaying messages on CB to her  10 miles away. There were other people doing the same thing  " Wall  said of the crash site.
"It's so amazing that you could look in the plane and see my face and touch my face " Howard said to  Wall .
"We pulled somebody out. That was you "  Wall  said.

Answer: Fireman Jamie Wall


Question: LeBron James  was experiencing pain and inflammation in  his  elbow over the summer so  he  changed  his  shooting motion to minimize the discomfort.
Through four games this season   James  is posting career-high shooting percentages across the board.
 James ' numbers may fall off as the season goes on  but it could be a positive new development in  his  game in  his  15h season.
In  his  15th season in the NBA   LeBron James  is shooting the ball differently and better than ever.
Through four games   James  is averaging 27 points per game while shooting 64% from the field  44% from three  and 88% from the free-throw line. All three percentages would be career-highs over the course of a season.
According to ESPN's Dave McMenamin  the change is not random  â James  changed  his  shooting motion during the summer to deal with an injury  and it appears to be helping  him .
 James  told McMenamin that shortly after the Cleveland Cavaliers' season ended   he  began experiencing discomfort in  his  elbow as it swelled to the size of a tennis ball.  James  was concerned enough to get an MRI on it  but it came back negative  with no structural damage.
Rather than halt  his  offseason work   James  began shooting with a higher release to minimize discomfort.
"It was just me "  James  told McMenamin. "I'm at a point now in my career where I know if I need to make an adjustment here or there."
 James  said the elbow inflammation went away on its own but  he  stuck with the new motion.
"I shoot it higher  " James  said. "When the swelling went down I just continued to do the same motion  the same motion. My free throws  my 3s  my pullups  all that."
The difference is not very noticeable. Here's a three-pointer  James  made in November of the 2016-17 season:
And a three-pointer  James  made on Tuesday against the Chicago Bulls:
Four games is a small sample size. Over the course of his career   James  has never shot better than 56.7% from the field  40.6% from three  and 78% from the free throw line.
According to McMenamin  Korver issued the 50-40-90 challenge to James â meaning a player shoots over 50% from the field  40% from three  and 90% from the free throw line for a season â and  James  balked slightly.
"I definitely got the 50 "  James  said. "The 50 ain't s---. I can shoot 50 in my sleep. I'm almost damn near 60. I can shoot 60 ... I can go 50-40-85. Maybe. We'll see."

James LeBron James
