Larry Ritsema was out for an early morning jog around his neighborhood one day. On a quiet street, he began to feel weak. Suddenly, everything went black. Larry fell to the ground.

    Less than a minute later, Tom Alguire passed by on his bicycle. He caught sight of a man lying on the roadside, so he jumped off his bike and ran over. He recognized Larry immediately, because he had been Larry's doctor for nearly 20 years.

    Dr. Tom felt for a pulse (脉搏) at first. Finding none, he began to give Larry first aid. It wouldn't restart Larry's heart, but it would keep the blood flowing until someone else arrive d. Tom could only hope someone would come by soon, at around six o'clock in the morning on a holiday weekend. Tom couldn't stop pressing Larry's chest to run for help — Larry's brain cells would die without the blood. And Tom didn't have a cell phone with him.

    Soon, a car did drive by. But the driver ignored Tom's appeal for help. What was he going to do? Tom was very worried. Finally, another car came down the road, driven by Michael Saliot, a U.S. Coast Guard Officer. Michael wasn't one to pass up a chance to help a person in need. He quickly dialed 911.

   Doctors then found that Larry had suffered a heart attack and there were severe blockages in two of Larry's major arteries (动脉). Only the timely arrival of Dr. Tom saved his life.

   How did Dr. Tom happen to be bicycling that morning, down that quiet street? It turned out that as Tom rode, his bike chain fell off. He spent about eight minutes fitting it back; otherwise, he would have seen nothing of Larry's problem.

    If you don't think technology can improve your trip better, meet Judy. When she recently checked into the Biu Hotel in Zurich, a clerk asked her to pay hundreds of dollars higher than the online offer. It was not a cheap stay, but it became more of one after she fired up the Booking. Com app she'd used to purchase her room on her smartphone. “As soon as I showed him the rate, he honored it,” Judy says.

    Technology may create challenges for travelers-indeed, it may have led to Judy's rate confusion in the first place-but it can also solve them. The solutions go beyond making sure of a hotel rate. The latest version of Booking.com is among the most feature-rich booking programs. Users can select hotels by location, make a secure booking and view the confirmed rate.

    Another pain point for travelers is traffic that eats away precious vacation time. There's a new app for that, called Commute. As the name implies, it's aimed at users who have to make the same trip every day. Just input basic information about your destination and expected leaving time, and the app will start sending you traffic data 15 minutes before you leave.

    Another source of travel-related conflict and confusion is money. That's particularly true when you're dealing with a foreign currency. The latest version of Travel Money Tracker helps travelers prevent currency mix-ups. It instantly converts(兑换) a country's native currency to yours, so you know exactly how much that Espresso(浓咖啡) in Milan costs in dollars. One extra feature is the ability to set up an alert that tells you when you're overspending, which can sometimes be a problem when you're on vacation. The only catch, of course, is that you have to remember to record all your purchases.

    The First Rule of Finance is to live within your means by spending no more than 80% of your take-home pay．If you take home $ 100 per week, spend no more than $80．

    But ever look at what people spend their money on? I have relatives and friends deeply in debt, spending $ 12 for every $ 10 they earn instead of the $ 8 you know they should be spending．When I see them, they're proud of their new whatever．"What do you think of my new truck?" asked one from the driver's seat．"Do you like my new shoes?" asked another on high heels．"Check out my new big screen．" said a third while holding the remote in his living room．We've all heard people fishing for compliments on their new toys ．

    Every one of them was proud of what they'd financed．They seem to have bought it for the purpose of being proud, of showing off, of keeping up with the Joneses．"Look at my new …?"is everybody's favorite phrase, even when the object in question isn't theirs at all and won't be new when they've finally paid for it, if they ever do．

    They're proud of being stupid．They think it's cool to drive the financed car, wear the financed shoes, and watch the financed TV, but to smart people, whose opinions are the only ones we should respect, these people look dumb as rocks．

    The Joneses, nine times out of 10, are financially stupid．That's why they have all that stuff on borrowed money．Why try to copy them? Worse, why try to impress them? Copy and impress smart people, the ones who own their stuff．If you want to impress smart people, debt is the last way to go about it．Trying to impress a money-smart person by going into debt is like trying to impress Olympic swimming champion Michael Phelps by drowning in a pool．Michael Phelps is impressed by good swimming and a money-smart person by good money management．

    As we all know,drinking beers while running can upset the stomach.However,that's all part of the attraction of the Beer Mile,a unique race that has participants competing in running and drinking.The Beer Mile Race started off as a tradition in 1990,when a group of Canadians thought it would be fun to race each other while drinking a few beers.But it has come a long way since then.The Beer Mile Race is now a major sporting event with around 100,000 official competitors,brand name sponsors and so on.In 2015,the first Beer Mile World Classic was held in San Francisco,where all of the record holders from Canada and the United States came together for the competition.But this year,the event was organized in London,in an effort to take in more competitors about the sport outside North America.

    The rules of the race are pretty simple: runners have to consume four beers before each of the four 400-meter laps making up the famous Beer Mile.The beers can come in bottles or cans but should not be less than 355ml and must be at least 5% alcohol.The drink like apple juice will not do.Runners must drink the beers within a 10 meter zone before the start/finish line and then they are required to tip the bottle/can over their heads to confirm it is empty.

    In the case of vomiting（呕吐）during the race,and yes,there's quite a bit of that during the Beer.Mile,offenders must complete one more lap at the end of the race.Organizers mention that even in the case of vomiting several times, only one more lap must be completed.

    This year,the Elite Men's race was won by Canadian Corey Bellemore,who also set a new world record with a time of 4 minutes and 34 seconds.“I just drink the beers as quickly as I could,hold them down and get the burps（饱嗝）out,”Corey said.“If you can drink a beer in 8 seconds and also run very fast with a feeling of vomiting,then you'll be fine like me.”

    ARNOLD Schwarzenegger is back, once again taking on his iconic killer robot role, the T-800, in August's new movie Terminator Genisys. While the T-800 model—even if it can be evil—has a fond place in moviegoers' hearts, the reality of autonomous machines is no joke, according to scientists.

    Autonomous weapons use artificial intelligence (AI) to choose targets without human help. They were described as “the third revolution in warfare, after gunpowder and nuclear arms” in an open letter signed by over 1,000 important technology figures in July. The list included British scientist Stephen Hawking and Apple co-founder Steve Wozniak. They asked governments around the world to ban autonomous weapons, warning that killer robots could start ethnic cleansings and an arms race.

     “They will look like tanks. They will look like battleships. They will look like jet fighters,” UK robotics professor Noel Sharkey told CNET, a leading technology website.

    But unlike these machines, which require a human hand in their action, so-called “killer robots” would have some decision-making abilities and the ability to act on their own.

     “If any major military power pushes ahead with AI weapon development, a global arms race is almost inevitable,” said the letter released at the 2015 International Joint Conference on Artificial Intelligence in Buenos Aires, Argentina.

    The idea of an automated killing machine was made famous by Schwarzenegger's first Terminator movie in 1984. While no red-eyed robots have been sent after human beings, the idea of AI being used as a weapon has gotten much more likely in the years ever since. The US military is already developing autonomous flying vehicles that can carry out all the steps of a strike mission without a human controlling them, according to a May report in Nature magazine.

    Scientists have even painted a destructive picture of autonomous weapons falling into the hands of terrorists or warlords hoping to carry out ethnic cleansings.

     “The development of full artificial intelligence could lead to the end of the human race,” Hawking said to the BBC in 2016.

Authorities are gradually waking up to the risk of robot wars. Last May, for the first time, the United Nations brought governments together to begin talks on autonomous weapons systems.

    Still, a ban on autonomous weapons is “easier said than done”, commented The Guardian. The dual (双重的) uses of the AI technology—for harm and for good—is difficult to manage. This is because the exact same technology can be used in a wide range of ways, the paper said.
