As the U.S. enters into colder weather, masks meant to prevent the spread of COVID-19 won't be the only face coverings one sees out on the street.It's led many to wonder: Is a mask necessary if I'm already wearing a scarf over my nose and mouth?Health experts say: Not so fast. Doctors say the best masks to wear during the winter are the same you would wear all-year-round.RELATED: How old is too old for a face mask?They also warn that when masks get wet -- say, due to breath perspiration catching on a face-covering -- they need to be laundered or replaced immediately."We have the paper, surgical masks – when those masks get wet, they need to be thrown away," said Dr. James Kravec, Chief Medical Officer at Mercy Health Youngstown in Ohio. "The cloth masks – when those get wet, they need to be laundered right away. Either mask, when they're wet, they're no longer effective."Kravec advised to put a COVID-preventative mask on first before layering up with a scarf, hat and gloves.

Over the past several years, major retailers have expanded their Black Friday shopping hours and some are even open on Thanksgiving Day. However, some don’t think stores should be open on the national holiday, so workers can spend time with their families. In fact, a survey conducted by 301

Arnold Kee has always pushed his two sons to do well in school. Then, an email he received from their high school last year alarmed him. It alerted parents about high levels of lead found in the water. “Fortunately, they've both done well, but it's the type of thing that makes you wonder would they have performed even better had they not been exposed to whatever lead was in the system,” Kee says. According to the Environmental Protection Agency (EPA), even low levels of lead can cause behavior and learning problems, including lower IQ scores. The school replaced water fountains and installed filters at the school designed to reduce lead. “What I like is the idea of the school being proactive and trying to address it, but then also the city itself trying to address it, because I do think it takes more than the just the city to be on top of what's happening,” Kee says. Washington, D.C. law now requires filters to be put on water fountains at schools, daycares and even at parks. However, D.C.’s efforts are the exception. An alarming report by Environment America found most schools are not doing enough to protect students from drinking water contaminated with lead. “We see pervasive contamination of drinking water at schools and pre-schools across the country,” says John Rumpler, co-author of the report.The report looked at states across the country and found most received failing grades. Millions of children are being exposed to lead from contaminated pipes and drinking fountains. “If your kid’s school was built before 2014, chances are the pipes, the plumbing, the fountains, the faucets have significant amounts of lead in them and those faucets and fountains should be replaced and filters should be put on,” Rumpler says.Rumpler urges parents to pressure their schools and lawmakers to make those changes. He also any parents concerned about lead contamination should talk with their pediatrician. 1937

New transportation options are showing up in cities across the country, including shareable bikes, electric scooters, and now mopeds are even starting to compete for street space.However, with all these new electronic transportation options there are safety concerns. Starting this weekend, 400 electric mopeds will be hitting the streets of Washington, D.C. One thousand of the mopeds are already available for rent in New York City. The company behind these electric mopeds, Revel, plans to expand to other cities. “The benefit is really simple. The way you have to think about it: this is almost always at least half the cost of Uber and Lyft and twice as much fun,” says Paul Suhey with Revel. They're part of a growing number of transportation options people can rent by using their cell phone app. Most major cities already have electric scooters and bicycles. Last year in the U.S., people took 84 million trips on bikes and scooters, according to National Association of City Transportation officials. However, the influx of rides is causing safety concerns, with some concerned the vehicles will add to the congestion on the road. “If you're having to be aware of either a cyclist, a scooter rider, now a moped rider, who may go in between cars, you have to be careful and watch out for each other as you're using these different modes of operations,” says Jeanette Tejeda de Gomez with AAA. She says research shows moped riders are more likely to be injured or die than those walking, biking or driving a car. However, Revel says helmets are included with each rental, riders have to be at least 21, have a driver's license and they screen the rider's driving record. “From our first couple months operating in New York, in over 300,000 rides, 99.99 percent have happened without incident, and we understand that safety record doesn't happen by accident,” Suhey says. Whether or not you’re ready to see these mopeds in your city, there’s no doubt on-demand transportation is now a driving force for new ways to get around. 2047
