5 . Are you relatively skinny but growing a “beer belly”?

Then don’t be surprised at your next checkup if the nurse measures your waistline to determine your healthy weight. That’s because research is showing that a protruding (鼓出的) belly may be a sign of VAT — a dangerous form of fat around organs deep inside your body. “Studies confirm that visceral (内脏的) fat is a clear health risk,” said Dr. Tiffany Wiley, a senior expert at the National Institutes of Health in Bethesda, Maryland. Unlike the fat just under your skin, visceral fat raises your risk for heart disease. Experts think that’s because visceral fat raises blood pressure and inflames (使发炎) tissues and organs.

However, you can’t assume you’re safe from visceral fat if your overall weight is healthy, experts stress. That’s because you can have dangerous visceral fat even if you’re not considered overweight — and not have any visceral fat even if you are overweight.

How do you know if your stomach is protruding into dangerous size? Do a check. Non-pregnant women with a waist size greater than 88 cm and men with a waist larger than 102 cm, are at higher risk according to the US Centers for Disease Control and Prevention. If you’re Asian, it drops to 80 cm for women and 90 cm for men. But it is only a rough measure. “The only sure way to know is to check your visceral fat levels on a CT scan or MRI,” say experts.

According to the AHA committee, the most salutary physical activity to “shrink” belly is aerobic exercise. Aerobic means “with oxygen”, so aerobic exercise increases your breathing rate and promotes the circulation of oxygen through the blood. This type of exercise makes the heart work more effectively and improves its ability to move oxygen-carrying blood with every beat. Speed walking, jogging, stair climbing, cycling and swimming are all examples of aerobic exercise.

“However, more studies are needed to determine the best physical activity, food and other lifestyle changes to reduce heart disease risk,” Dr. Tiffany Wiley added.

6 . Japanese automaker Toyota says it will team up with the country’s space agency to develop a vehicle called the Lunar Cruiser to explore the moon. The name comes from a popular Toyota vehicle called the Land Cruiser. The company said it plans to launch the vehicle in the late 2020s. After that, Toyota said the vehicle could assist people living on the moon by 2040 and could possibly be sent to Mars as well.

Takao Sato heads the company’s Lunar Cruiser project. He told The Associated Press the vehicle is based on the idea that people eat, work, sleep and communicate with others safely in cars. He hopes theLunar Cruiser can serve the same purpose in space. “We see space as an area for our once-in-a-century transformation, ” Sato said, “By going to space, we may be able to develop telecommunications and other technology that will prove valuable to human life. ”

Another company, Gitai Japan Inc., is partnering with Toyota to develop a robotic arm for the Lunar Cruiser. It will be designed to perform jobs such as carrying out inspections and maintaining the vehicle. The company said the arm will be built to work with different tools. These tools could be used to study the moon’s surface more closely.

Interest in space has been growing in Japan in recent years. Japanese space exploration company iSpace announced last April that it would transport an explorer belonging to the United Arab Emirates (UAE) to the moon in 2022. Japan’s iSpace will provide the lander to carry the UAE’s rover(探测器).

The company plans to launch the lander on a Falcon 9 rocket built by American company SpaceX. Japanese citizens followed the trip to space last year of billionaire Yusaku Maezawa. He spent 12 days aboard the International Space Station. Maezawa also plans in the future to orbit around the moon on a SpaceX’s Starship spacecraft.

Toyota engineer Shinichiro Noda said he thinks the lunar project can extend the company’s tradition of serving customers to a place beyond Earth. He said Toyota currently has vehicles almost everywhere. “But this is about taking our cars to somewhere we have never been, ” Noda said.

9 . The Greenwood fire took its name from the nearby lake where lightning struck on Aug.15, causing a wildfire that burned for weeks. Fueled by drought and wind, its persistence dominated headlines for much of late summer and early fall in Minnesota. When the last flames were finally put out, the northern Minnesota fire had consumed nearly 27,000 acres, countless firefighting resources, and at its worst, the lives that some had built around nearby McDougal Lake. Vast areas of forest were left burned-out, with the black and bare remains of what were once massive pines.

But, despite the destruction left behind, Mother Nature is set to a comeback. When organic matter is burned from the forest floor, seeds dropped by plants and trees begin to take hold, with the sprouting species emerging first. The trees above have died, which sends a chemical signal to the root system that is actually more expansive than just under that tree, and that chemical response encourages those root systems to re-grow. Ten years ago, a fire ripped through 93,000 acres of Minnesota forest in and around the BWCA. Today, that burnt area's rebirth is well underway.

"Here in the Pagami Creek wildfire scar, we have Jack Pine, Red Pine, Black Spruce, Aspen and paper birch-those are our main species, those are the ones that are growing quickly. It's 10 years on, and these trees are 10 to 15 feet tall in many areas," said Kyle Stover from the U.S. Forest Service.

A wildfire kills most things in its path, but despite the flames and intense temperatures, rarely is everything reduced to ashes -and that plays a key role in a forest's regeneration. Just one year after the fire, the survivors dominate the forest, and grasses replace the burnt ground. Wildflowers are abundant bushes and small trees have started to grow, and Jack Pine returned. So, it's an amazing ecological system of creating new forest life when it appears that all is lost, one that has evolved throughout the ages, where fire has always played a vital role.

10 . How to Be a Good Upstairs Neighbor

One must remember to be polite when living in an apartment building. You may unintentionally bother your neighbors with actions that you think to be harmless.     1     Living upstairs, you must always be aware that everything you do may be heard by those who live below. This doesn’t mean that you have to completely change your lifestyle, though.

    2     This will greatly reduce the sound of your footsteps, thus limiting the sound your downstairs neighbor will hear. You should always remember to change your shoes when entering your apartment to ensure that your downstairs neighbor doesn’t hear you walking around.

Place carpets in your apartment if you have hardwood floors. Doing so is another way to decrease the sound of steps coming from an upstairs apartment. You can also put your furniture on these carpets.     3    

Close your windows when you can. A floor is usually about three meters high, so it’s quite easy to hear your conversations.     4     Therefore, whenever you are watching TV or listening to a radio, try to keep your windows closed as much as possible.

Do your cleaning on weekend afternoons.     5     Doing such housework at 3:00 pm on a Saturday is much better than doing so at 9:30 on a Tuesday night.
