With flu season underway and COVID-19 sweeping the nation, doctors say boosting your immunity the natural way can reduce your chances of getting sick.Health experts say to start by reducing your sugar intake. According to Dr. Stephen Sinatra, sugar can stifle the activity of white blood cells making it harder for your body to fight against illness.But with the holiday season upon us, fighting the sugar craving won't be easy. Cardiologist Stephen Sinatra suggests satisfying that sweet tooth the healthier way by adding berries to your small slice of pumpkin pie. Berries have bioflavonoids, carotenoids and polyphenols, which support the immune system.Consuming Vitamin C rich foods, such as peppers, broccoli, and oranges, are also essential to avoid respiratory infections. Zinc, found in meat, seeds and nuts, is just as important. According to the International Journal of Infectious Diseases, a zinc deficiency could make battling the virus harder and could lead to a long hospital stay and higher death rates.As for Vitamin D, Dr. Sinatra says it’s like a knockout punch against COVID. But getting enough of it could be a challenge this time of year. With more people at home under quarantine and less sunlight during cold months, Dr. Sinatra recommends at least 2,000 to 5,000 units of Vitamin D3 a day during the pandemic.Finally, take quercetin. It's a bioflavonoid found in onions, black tea and green apples. Also, be sure to get plenty of sleep and exercise. Stepping up your nutrients will put you on a path to boosting your body’s natural defenses.This story originally reported by Stacy-Ann Gooden on PIX11.com. 1639

We've heard about telehealth for people, but now it's there for animals too. According to the American Veterinary Medical Association, there's been a significant increase in telemedicine, and some veterinarians are entirely virtual.The pandemic has proven we can do almost anything from our couches, computers and phones. We've grown accustomed to all things virtual and it seems our pets are used to it too.“It really highlights the value of something like this and it also really highlights where society is living. Even before the pandemic, turned to google, turned to the internet first. It's our first step in almost everything,” says Dr. Sarah Machell.Machell is the lead veterinarian for Vetster, which provides on-demand virtual care for your pet.“Consultations, meeting pet owners in their homes, where they are with their pets, and helping to address urgent and preventive care health conversations to them,” Machell said.She says the company, which launched in October 2019, wasn’t formed because of the pandemic, but they certainly evolved at the right time."The veterinary clinics themselves are feeling a really heavy surge with the pandemic. It’s a pretty crushing situation for them. We already as a profession had some staffing challenges, not enough veterinarians for how many pets and pet owners there are,” Machell said.Pet owners, she says, often have a hard time getting an appointment. Or they have to wait in their cars with their animal outside of their clinic. And, according to Vetster, 50% of pet owners don't even have an established home clinic.“There was a poll recently that showed 37% of American households welcomed a new pet into their home during the pandemic. Pandemic puppies are a real thing,” Machell said.“I think it offers a great addition to the tools I have at my disposal. Telehealth can be used very much the same way,” said Dr. Douglass Kratt, president of the American Veterinary Medical Association. The AVMA serves roughly 96,000 veterinarians across the country. They've been through a lot this year, adjusting to new norms, like all of us. As in human medicine, they've had to perfect, or initiate virtual options.“It doesn’t replace your veterinarian. What it does is help your vet better serve you and your family member,” Kratt said.Kratt admits there are some obvious challenges.“I can’t hear if your dog is coughing, I can’t listen to the heart and lungs via telemedicine so that wouldn’t be amenable,” Kratt said.He says, however, it's effective overall, and especially worthwhile if it's with your established vet. But if you don't have one, Vetster and other businesses like it aim to help.“There are so many pets and pet owners who sometimes sit on things and aren’t sure if they need to go into a clinic, really appreciate that piece of mind in the middle of the night that no, you don’t need to pack yourself up and get into a vet clinic. This is something you’re okay to wait until the morning,” Machell said.And she says they're prepared to help all animals from pocket pets to exotic and large animals. It’s yet another adjustment and another pivot in 2020. 3131

Whether planning necessary travel in the near term or fantasizing about vacationing in the ever-longer term, you might be curious how the coronavirus pandemic has affected airfare prices.We compared data from our points and miles valuations analysis to determine where and how airfare has changed since this time last year. We looked at the same routes, airlines and booking time frames for both 2019 and 2020, ensuring an apples-to-apples comparison.Although air travel has picked up significantly since the lows in April, the Transportation Security Administration is still reporting about 63% fewer daily screenings than this time last year. Has this drop in air travel demand led to a significant price drop?The short answer is: Yes, prices have fallen.Prices have dropped, but mostly in the short termThe average cost of a domestic round-trip ticket fell 23% in 2020, from 7 in 2019 to 4.This price drop is striking but not surprising given continued low demand. But the trend becomes stronger when breaking out the booking date data, with those made within 15 days dropping much further than bookings made six months in advance.The plot thickens.Airfare for long-term bookings has remained flat year over year. If you book a flight for six months from now, you’re likely to pay roughly the same price as you would have last year. But closer-in bookings, within 15 days, are not only far cheaper than they were in 2019 but also cheaper than long-term bookings.This turns conventional airfare-booking wisdom on its head. Usually, we would recommend booking flights as far ahead as possible to secure low fares. But booking too far in advance is now a recipe for getting fleeced.? Learn more: How to plan holiday travel for maximum flexibility in 2020What’s going on?The management of supply and pricing is usually an exquisitely orchestrated dance in which airlines ensure that every flight is filled to near capacity and every price is competitive. This usually means ramping up prices for nearly full flights at the last minute, when competition becomes stiffer.However, now that demand has dropped and airlines are actually falling over themselves to reduce flight capacity, the game has changed. Airlines are now competing with each other for last-minute bookings, which drives down prices. And they seem to be making up revenue by raising prices on longer-term bookings made by those few brave souls willing to plan in advance. In other words, it’s a buyer’s market for close-in bookings.Of course, these pricing dynamics, like everything this year, are liable to change by the week. If you’re thinking about booking a particular route, set up a price alert on Google Flights or another travel search tool and keep an eye on how the airfare winds are blowing.What do these unusual airfare trends mean for you? Keep it simple: Avoid booking months in advance, set up a price alert and try to shed the normal (and normally smart) habit of avoiding last-minute bookings.More From NerdWalletShould I Pay for My Hotel Using Cash, Points or Both?5 Travel Writers ‘Draft’ Their Favorite Airlines(How) Should I Travel for the Holidays?Sam Kemmis is a writer at NerdWallet.

When it comes to saving lives, seconds count. And now, thanks to improving technology, drones are proving to be a game changer in an emergency.Dozens of people’s lives were saved last year with the help of drones, according to drone maker DJI.  The company said from May of 2017 to April of 2018, 65 people were rescued with the help of a drone. DJI reviewed media reports to come up with that number and included documentation in its recent report released this year.Firefighters, search and rescue teams and other members of law enforcement are using drones to survey an area much faster from the air than people can on the ground.“During a search and rescue operation we can see body temperature, Romeo Durscher, DJI’s Public Safety Integration Director, said.Drones carry more than simple cameras. They are now built to send back infrared images.Aeryon Defense USA, of Denver, has drones that can carry upwards of four pounds of payload. The company sells drones that can be used by police agencies and the military."That allows you to hook in a medical kit, radio, food, water (or) ammunition to provide life sustaining equipment," said Mark Holden of Aeryon Defense USA. “We can carry water, enough for one day, food, even ammunition resupplies and some explosives as well.”The company’s drones can also be programed to single out a person moving in the camera’s view, but ignore a tree blowing in the wind or wildlife.“This is just the beginning. Everything we do is about taking the load off the end user. We want to replace human functions on the battlefield with a robot,” Holden said.Drones have helped find a woman with dementia in Randolph County, North Carolina. She had wandered into a nearby field. Drones dropped a life preserver to flood victims in Sichuan, China before rescue crews arrived to save the victims. An infrared camera-equipped drone located a crash victim who became unconscious after leaving his car to get help. A similar camera also was used to locate lost tubers on a river in Vestavia Hills, Alabama.Technology allows drones to carry more weight than before. In the last one-and-a-half to two years, drone makers have improved how drones fly in difficult weather conditions."Search and rescue operations rarely happen on a beautiful, no wind kind of day so we had to design them to withstand the snow, the wind, and the rain,” Durscher said.They can help save the lives of rescuers too."You know what's ahead of you. It can alert you of a big cliff or flooded river,” Durscher said.Drones used by most rescue agencies run as much as ,000 to ,000. 2642

  

With a crowd of onlookers gathered around, New York Police officers encircle a woman and her child on the ground.One officer reaches down and begins to pull. The officer yanks harder, and harder, and the woman's cries become louder."You're hurting my son! You're hurting my son!" she yells.A tug of war ensues, and as noise from the horrified crowd builds, an officer brandishes a yellow stun gun and begins to point it around the room, a government welfare office in Brooklyn.The stunning and hectic scene, captured on video and posted to Facebook, ends with the woman in handcuffs escorted from the scene — and her 1-year-old son elsewhere. A family member took custody of the child following the arrest, the NYPD said.The forceful arrest of the unarmed mother at a social services office has caused a significant backlash, particularly from those who saw it as an unnecessarily violent escalation and a symbol of how the poor are treated in America."Being poor is not a crime. The actions of the NYPD in this video are appalling and contemptible," said Letitia James, the Public Advocate for New York City.Facing criticism, the NYPD and the New York City Human Resources Administration are now reviewing that December 7 arrest."Video images of the incident in the 84th precinct are troubling," the NYPD said in a statement, adding that the review will "include examination of all available video of the incident."Corey Johnson, the speaker of the New York City Council, said it was "unacceptable, appalling and heart breaking.""I'd like to understand what transpired and how these officers or the NYPD justifies this. It's hard to watch this video," he said on Twitter.On Facebook, James called for a full investigation into the officers' conduct and said the results should be made public. She also called for the officers involved, including their assigned supervisor, to be assigned to desk duty until an investigation is complete."No mother should have to experience the trauma and humiliation we all witnessed in this video," she said. 2056
