We've all heard exercise helps you live longer. But a new study goes one step further, finding that a sedentary lifestyle is worse for your health than smoking, diabetes and heart disease.Dr. Wael Jaber, a cardiologist at the Cleveland Clinic and senior author of the study, called the results "extremely surprising.""Being unfit on a treadmill or in an exercise stress test has a worse prognosis, as far as death, than being hypertensive, being diabetic or being a current smoker," Jaber told CNN. "We've never seen something as pronounced as this and as objective as this."Jaber said researchers must now convey the risks to the general population that "being unfit should be considered as strong of a risk factor as hypertension, diabetes and smoking -- if not stronger than all of them." 799

With its low air pressure, Hurricane Michael unofficially sits as the third-strongest landfalling hurricane to strike the United States. Having such a tremendously low air pressure typically causes storms to have strong winds, and Michael was no exception. Hurricane Hunters from the Air Force and NOAA estimated Michael's lowest pressure was 919 MB at landfall. The only two hurricanes with a lower pressure at landfall to hit the United States were the Labor Day Hurricane of 1935 and Camille of 1969.Also based on estimates, Michael had top winds of 155 MPH, which is just below Category 5 status. Based on top winds speeds, Michael was tied for the sixth-strongest landfalling hurricane in US history, tied with Hurricane Maria in 2017 and "Guam" in 1900. In terms of air pressure, Michael was 1 MB stronger than Katrina in 2005 and Maria in 2017 at landfall, and 3 MBs stronger than Andrew of 1992. Michael's top winds at landfall were well ahead of Katrina's top winds at landfall of 130 MPH, on par with Maria's top winds at landfall of 155 MPH, but below Andrew's top winds of 165 MPH.But in the immediate aftermath of Andrew, it was declared a Category 4 hurricane at landfall. It was not until years later when the National Hurricane Center concluded that winds in Andrew were greater than 157 MPH, marking the only Category 5 hurricane to strike the US since Camille in 1969. Like Andrew, Michael continued to strengthen all the way until landfall. In just three days, the storm went from a tropical storm to a high-end Category 4 hurricane. Other reasons Micheal will be notable:- Michael was just the sixth hurricane of at least Category 4 strength to hit Florida since 1950.  1752

White House counsel Don McGahn's final day at the White House was Wednesday, sources say.A White House official and a source with knowledge of the matter confirmed his departure to CNN.McGahn has been planning to leave the White House, but a source told CNN his departure was expedited after President Donald Trump said Tuesday he had selected Patrick Cipollone as his successor.A source said McGahn had a 20-minute farewell meeting with Trump Wednesday. The source called it a positive departure but both Trump and McGahn recognized it was time for him to go. The source said McGahn didn't want to stay on and the President didn't want him to stay.The source, "Typically you would have the incumbent stay until the successor was ready to take his place. But in this case McGahn was tired of the President and the President was tired of McGahn."McGahn leaves his post after serving as White House counsel through the tumultuous first 18 months of Trump's presidency, steering the White House's handling of the Russia investigation and responding internally to the President's mercurial moods as the investigation ballooned.His departure is another one from the handful of top aides who worked on the Trump campaign before joining the White House. McGahn served as the Trump campaign's top attorney throughout the GOP primary and 2016 presidential election, becoming a trusted adviser to the future President in the process.But McGahn immediately faced controversy in his earliest days at the White House, beginning with acting Attorney General Sally Yates' warning to McGahn that then-national security adviser Michael Flynn could be blackmailed by Russia and that he had likely lied to Vice President Mike Pence. Flynn was forced to resign after reports revealed Yates' warning to McGahn about Flynn's conduct.As the Justice Department and congressional investigations into Russian meddling in the 2016 election heated up, McGahn found himself increasingly at the center of Trump's and the White House's response to the investigation.And when Attorney General Jeff Sessions faced pressure to recuse himself, Trump enlisted McGahn to urge Sessions not to take that step. Sessions eventually did recuse himself, giving his deputy, Rod Rosenstein, the ultimate authority to appoint a special counsel.McGahn threatened to resign in the summer of 2017 after Trump ordered him to fire Robert Mueller, the special counsel investigating potential collusion between the Trump campaign and Russia's election meddling and questions of obstruction of justice.For McGahn, the President's order to fire Mueller was a bridge too far -- with the White House counsel refusing to follow through on the order, a person familiar with the matter told CNN. The New York Times first reported Trump's move to fire Mueller and McGahn's refusal to carry out the order.The slew of incidents involving the President and McGahn amid the Russia investigation made the White House counsel an important witness in Mueller's investigation, with McGahn sitting for interviews with Mueller's team in December.Before joining the Trump campaign and the White House, McGahn worked at the powerful DC law firm Jones Day and previously served as a commissioner on the Federal Election Commission. 3265

WISCONSIN — An update on the expected re-entry of China's old Tiangong-1 space station has been announced.The space station was initially launched in September 2011. An official Chinese statement declared that Tiangong-1 terminated its data service on March 21, 2016. Since the Chinese government has lost control of the station, it's hard to predict where and when it will fall.The European Space Agency predicts the space station will fall back to Earth between March 30 and April 6, while research organization Aerospace predicts a re-entry on April 1, give or take 4 days.Aerospace says it is much easier to predict a re-entry time than a location. This explains the wide scope of possible re-entry zones, which both Aerospace and other organizations predict will be between 43 degrees North and 43 degrees South latitudes. 855
