[EX Q]: ABC News chief medical correspondent  Dr. Jennifer Ashton  gave up alcohol for the month of January.
This month  instead of "going dry "  Ashton  is focusing on increasing something in  her  diet: Water.
âI am like a camel â  Ashton  said today on âGood Morning America.â âMost days  the only water I consume comes in the form of coffee  which does count but it also can dehydrate you a little bit.â
âI have a bottle in my refrigerator and I make sure I go through two of them a day â  Ashton  said of her new habits.
Climbing on board with  Ashton  in this monthâs âGMAâ health wellness challenge are co-anchors Robin Roberts and Lara Spencer.
 Ashton  described drinking more water as an âeasy tweakâ that could have noticeable results.
Foods with the highest water content include fruits and vegetables like watermelon  lettuce and broccoli  according to  Ashton .

[EX Q]: LOS ANGELES (Reuters) - If  Walt Disney Co (DIS.N) buys some Twenty-First Century Fox (FOXA.O) businesses    it  could provide a quick path for the traditional media giant to create a substantial competitor to Netflix Inc (NFLX.O) in the battle for TV and movie viewers.

The two companies reportedly held talks in recent weeks about a potential sale of  Foxâs FX  and National Geographic channels   its  movie studio and some other international assets to Disney  according to media reports. The discussions had stopped as of Monday but could restart  the reports said.
Investors who have driven Netflix shares to record highs this year were selling on Tuesday  sending the companyâs stock down more than 2 percent. Disney and  Fox  shares rose roughly 1 percent each as analysts said a deal between the two media giants could benefit Disneyâs planned streaming push.
With Fox  Disney in the future could yank  Fox  programming from Netflix and put shows like âThe Simpsonsâ and movie franchises including âAvatarâ alongside Disney classics such as âBeauty and the Beastâ plus âStar Warsâ and Marvel films.
That would leave a hole in Netflix.  Fox  made up 17 percent of Netflixâs top-rated shows by IMDb as of June  while Disney made up 7 percent  according to MoffettNathanson and YipitData.
 Disney and Fox  also each own roughly 25 percent of streaming service Hulu  which could serve as another platform for content.
Disney   Fox  and Netflix had no comment.
âThatâs why  we  got into the originals business five years ago  anticipating it may be not as easy a conversation with studios and networksâ to license their programming  Sarandos said.
Disney will be starting its online service more than a decade after Netflix  which now boasts 109 million streaming customers around the world. Disney could expand its global reach if it acquires Fox TV channel Star India and the companyâs stake in European pay TV provider Sky Plc (SKYB.L)  which already has made inroads in the streaming market.
Needham & Co analyst Laura Martin said Disney needs to buy a film library from Fox or another big company to compete directly with Netflix. âDisneyâs libraries are very high quality  but they are very small â Martin said. âThey could not do it alone.â

[EX Q]: When the three-pointers are falling and the good vibes are flowing   Otto Porter Jr.  celebrates  his  shots with a signature pose. As  he  jogs back on defense   Porter  leans forward  holding three fingers so close to the court  he  could pick up loose change.
On Friday night  the threes kept falling  the vibes were right  and  Porter  often did  his  thing in the Washington Wizardsâ 121-103 win over the Houston Rockets.
 Porter  made the deep perimeter  his  home against the NBAâs leading three-point shooting team. In the first quarter  Porterâs three makes from beyond the arc matched the team total for the Rockets.  He  added three more in the fourth  getting an early rest as Washington turned a showdown with one of the top teams in the Western Conference into a blowout.
 Porterâs  seven three-pointers tied a career high and  he  finished with a game-high 26 points (on 9-for-16 shooting) to go with a team-high seven assists. Bradley Beal and Kelly Oubre Jr. added 21 points each  and John Wall finished with 17 and four assists but defined his game on the defensive end with five steals.
