When it's one hundred degrees in Washington D.C., it's hard to get outside to do anything. But for supporters of the late Congressman John Lewis, the opportunity to pay respects to the civil rights icon is worth the sweat. "We knew before coming out here that the heat index would be 105," Lenora Simpson said. "He never stopped, he never gave up, he was always fighting," Simpson added. "I always tell my grandchildren if it wasn’t for the pioneers we don’t know where we would be," Simpson added. Simpson, like so many men and women lining up outside the U.S. Capitol, never met Lewis. They just know his legacy as a fighter for equality. 27 year-old Joshua Maxey, however, did meet Lewis five years ago during an interview. He stood in line Monday thinking of the advice Lewis gave the man. "[He said] now it’s your time, It’s your generations time to pick up the mantle, obviously those words are still stuck with me today," Maxey said. 949

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

With just over a month until the election, Florida and Arizona are emerging as battleground states that are neck-and-neck for President Donald Trump and former vice president Joe Biden.For the first time in 2020, Trump has a slight lead in Florida, according to the Washington Post-ABC News poll. Among participants who said they are likely voters, Trump leads 51-to-47 percent, however this is considered within the margin of error.The poll points out Biden has a 13-point lead among Hispanic registered voters in Florida; four years ago, Hillary Clinton had a 27-point lead among Hispanics and still lost the state.In Arizona, among likely voters, the poll shows Trump and Biden at 49-to-48 percent. Arizona has voted for the Republican presidential candidate for every election since 1952 except once, the re-election of Bill Clinton in 1996.Researchers of this poll note that these percentages are so close the difference is not statistically significant. The margin of sampling error is 4 points among Florida results and 4.5 points among Arizona results.Trump won Florida and Arizona in the last election. In Arizona, Trump won in 2016 by about 90,000 votes. In Florida, Trump won by just over 100,000 votes.When it comes to the issues, Trump gets credit for being trusted to handle the economy, despite the current pandemic-fueled recession. In Florida, registered voters in the survey said they trusted Trump with the economy over Biden 52-to-41 percent. In Arizona, the spread is higher, with registered voters preferring Trump 56-to-41 percent.The economy appears to be the top issue for many this election cycle. About 31 percent of registered voters in Florida said the economy is the single most important issue, and 33 percent of those in Arizona.In handling the coronavirus pandemic, more registered voters trust Biden over Trump, with 48-to-43 percent in Florida and 49-to-45 percent in Arizona. In both states, 57 percent of participants said they were worried about catching the coronavirus.Biden also leads in handling health care, crime and safety, discouraging violence at political protests, and equal treatment of racial groups.Trump’s overall approval rating among registered voters is 47 percent in both states.There is also a big split in how voters of different parties plan to vote on Election Day. In both Florida and Arizona, more than 70 percent of registered Republicans plan on voting in-person on Election Day. Democratic participants are more likely to vote early or absentee/mail-in, more than 60 percent.This latest poll was conducted by landline and cell phone interviews between September 15-20 among 765 registered Florida voters and 701 registered Arizona voters. 2712
