question:
Actor John Bradley  who plays Sam  Tarly  told TV Guide that characters are going to keep being pushed by new elements and traveling the seven kingdoms deeper and faster than ever before.
"Each of the characters this year is placed in a completely alien environment at some point in the season that they've never been placed in before "  Bradley  said. "The thrill is seeing how they react to it and how they respond... This season  I think  more than any other is stretching these characters."
But  Bradley 's comments are intriguing from a character perspective. An alien environment isn't necessarily a physical place; it's an unfamiliar situation (Arya  no longer sniffing out traitors)  an important task (Cersei trying to play nice with others)  or a new threat (White! Walkers!).
"The stakes definitely feel ramped up  " Bradley  told TV Guide. "We know that we've got a real job to do. This has been a part of people's lives for so many years. This is our eighth season  and we are kind of feeling the pressure to get it right because we want to satisfy people...we just kind of want to give them an ending that they deserve."
answer:
'Game of Thrones' characters will keep traveling in Season 8


question:
"Did they cut more calories from their diet ... or did they become more physically active?" asked study author Kevin Hall   a senior investigator with the National Institute of Diabetes and Digestive and Kidney Diseases.
 Hall  had been "puzzled by how quickly the contestants were losing weight." So he contacted the show's physician and began studying the season eight contestants.
Early on   Hall  observed that weight loss was better predicted by food intake  not physical activity alone. But in the long term  the opposite was true.
"You have to be very physically active in order to keep the weight off  " Hall  said.
 Hall 's findings echo previous studies that promote more exercise for long-term weight loss maintenance. However  experts caution that doesn't mean people can neglect their diets in the long run  either.
This method  however  was not able to tell how much of the physical activity was due to normal daily activities -- like cleaning the house or walking the dog -- versus following a workout plan   Hall  said.
Six years later  however  the contestants' resting metabolisms still hadn't sped back up   Hall  showed in a study last year.
For  Hall   metabolic changes are just one part of the puzzle. Genetics may also play a role  as well as social factors that can make it hard for some people to incorporate so much exercise in their daily lives.
 Hall  added that it's not necessarily those who were most physically active during the competition who kept it up six years later.

question:
In a deposition more than a year later  which the NBC station also aired  the video was shown to  Wanda Nuckles   the nursing supervisor on duty that night.
âWould you agree it appears as though heâs gasping for air?â the questioner asked  Nuckles .
Staff returned to the room nearly an hour later and found Dempsey unconscious  the NBC station reported. Nearly another full hour passed before anyone called 911  according to the station. At that point   Nuckles herself  was called up to the room.
Earlier in  her  deposition   Nuckles  testified that  she  ran across the nursing homeâs courtyard to Dempseyâs room  where  she  said  she  and a second nurse took turns performing constant CPR. âUnless a doctor says stop  you have to continue â  Nuckles  told the questioner. âThatâs always been the rule.â
But the questioner played a clip from the video that told a different story. In the video   Nuckles  walked into the room shortly before 6:30 a.m.  where another nurse stood by Dempseyâs bed. Someone flipped the dying manâs sheet up  and someone lowered his bed. But neither  Nuckles  nor the nurse appeared to touch Dempseyâs chest.
âContrary to the way you testified previously  thereâs no one doing CPR  is there?â the questioner asked  Nuckles  after playing the clip.
âNo â  Nuckles  said.
A few minutes later  a third worker joined  Nuckles  and the second nurse. Dempsey was still not moving  and still no one was attempting CPR.
The NBC station reported that the nurses were having trouble getting Dempseyâs oxygen machine to work by 6:30 a.m. â at which point in the video  Nuckles  pressed both hands onto Dempseyâs mattress and someone laughed.
âMaâam  is there something funny that was happening?â the questioner asked  Nuckles  in the deposition.
âI have no clue  sir â  she  said. âI canât even remember all that.â
A minute later   Nuckles  finally attempted CPR on Dempsey.  She  pumped his chest half a dozen times in the video  then stopped.
 Nuckles  and the other nurse in the video lost their licenses after the Georgia Board of Nursing learned of the video last year  according to NBC.  Nuckles  could not be reached by The Washington Post.
answer:

A dying vet needed CPR. Hidden video shows his nurse laughing instead.
