It can be hard to squeeze in time to exercise, but a new study suggests that even just five to 10 minutes of running per day can make a big impact on health and reduce the risk of heart attacks and strokes.

Published Monday in the Journal of the American College of Cardiology, the report states that when looking at runners and non-runners, runners had a 30 percent lower risk of death from all causes, and a 45 percent lower risk of death from a stroke or heart attack. Doctors once thought that 75 minutes of vigorous activity per week was necessary, but that's probably not the case, researchers say.

"Our study showed that only fairly small doses of running were needed to produce these profound benefits," co-author Dr. Carl Lavie of the John Ochsner Heart and Vascular Institute in New Orleans, told NBC News. "Even running less than six miles per week, running less than an hour per week at paces less than 10 minute miles were still producing very substantial reductions in cardiovascular mortality."

Researchers followed 55,137 adults between the ages of 18 and 100 for an average of 15 years. When the study began, none of the participants had ever suffered from a stroke, heart attack, or cancer. By the end of the study, 3,413 died, 1,217 from a stroke or heart attack. Those who ran even for just a few minutes a day were less at risk. "There is misconception that you have to be a marathon runner to have an effect on health," Dr. Vonda Wright of the University of Pittsburgh Medical Center's Lemieux Sports Complex told NBC News. "But that is not true. It may be that a very small daily investment makes a difference — and purposeful choices." Catherine Garcia

Tunisian President Beji Caid Essebsi declared a state of emergency in Tunisia on Saturday, the state news agency reports. In June, a gunman killed 38 foreigners and injured 39 others in a beachside terrorist attack. Security officers killed the gunman after the attack had stopped.

It's the second terrorist attack Tunisia has seen in three months, The New York Times reports. The state of emergency allows Essebsi to authorize military operations in Tunisia's own cities. Julie Kliegman

Eight-time defending champion Joey Chestnut met his match Saturday in Matt "Megatoad" Stonie, who won Nathan's Hot Dog Eating Contest on Coney Island. Stonie downed 62 dogs and buns in 10 minutes, two ahead of Chestnut.

"I trained hard for this, and I came prepared," Stonie said.

Chestnut still has claim to the contest record, though, since he polished off 69 dogs in 2013 — good news for those of you who worried the man famous for binge-eating fast food might've lost his dignity with his defeat. Julie Kliegman

Pot economics

The legal pot market began in Washington on July 8, 2014, and just one year later, it's making bank. The state's 160 stores earn $1.4 million per day. Between state and local governments, pot sales have rolled in about $70 million in taxes, The Associated Press reports.

Business might be good, but all those taxes — on top of federal ones — hurt growers.

"I'm basically doing this for free," James Lathrop, who owns Seattle's first legal shop, told AP. "Nobody's gone out of business, but I'm not driving a new truck either."

So next time you're in Washington, maybe you should think about kicking back with some weed — you know, just for the sake of supporting small business. Julie Kliegman

Donald Trump took to Fox & Friends to defend the comments on Mexican immigrants that landed him in hot water this week with companies like NBC, Macy's, and most recently NASCAR.

"The crime is raging and it's violent. And if you talk about it, it’s racist," he said, referring to accusations against his presidential campaign kickoff that many Mexican immigrants are rapists and drug users.

Trump admitted he didn't realize the backlash would be quite so severe, calling himself a "whipping post." Watch the full interview here. Julie Kliegman

NASCAR joined a long list of companies cutting ties with billionaire and Republican presidential hopeful Donald Trump following his controversial remarks last month about Mexican people. The auto racing governing body will not hold its Xfinity and Camping World Truck series banquets at the Trump National Doral Miami as originally planned, USA Today reports.

"Our company will not stand to support any person or organization that associates with such beliefs and we feel strongly about distancing ourselves from any negative and discriminatory comments made against any gender, ethnicity, age group or so forth," said Camping World CEO Marcus Lemonis, who vowed to not attend the awards if held at Trump's hotel. "I would hope that the entire NASCAR organization would agree with my sentiments."

In his campaign kickoff, Trump classified most Mexicans immigrating to the U.S. as rapists and drug users. NASCAR joins companies like NBC Universal, Univision, and Macy's in denouncing the comments. Julie Kliegman

A Florida judge had one unusual question for the burglary suspect in her bond court: Did you go to middle school with me?

Arthur Booth, 49, was arrested in Hialeah on charges of burglary, grand theft, fleeing, and resisting arrest, NBC 6 South Florida reports. Judge and former middle school classmate Mindy Glazer's question shocked him. He immediately teared up, held his head, and repeated "Oh my goodness."

Glazer had some encouraging words for the man she called "the nicest kid in middle school."

"Good luck to you sir," she said. "I hope you are able to come out of this OK and just lead a lawful life."

JetBlue ran its first official direct flight from New York City's John F. Kennedy Airport to Havana's José Martí International Airport on Friday, the first in a planned series of weekly charter flights.

It's the first major airline to do so, though smaller outfit Sun Country was the first to start servicing the two cities, Time reports.

JetBlue also runs flights to Cuba from Florida cities following the easing of travel restrictions earlier this year as the two nations work to restore diplomatic ties after half a century without relations. Julie Kliegman
