5 Lifestyle Choices You Will Feel in Your Bones

YOU SPEND TOO LITTLE TIME ON THE MOVE

"Bone is a living tissue," says Jonathan Lee, a physician at Montefiore Health System in New York City. "The more you use it, the more it will adapt and strengthen. Likewise, if it is not subjected to loading, it will waste away. " The solution? Weight-bearing exercise-even just walking. Strength training Counts too

YOU EAT SALTY SNACKS

A study from Japan showed that women over fifty who had high sodium (钠) intakes were more than four times as likely to have a fracture (break of.bones) as those with low sodium intakes. That's because as the kidneys(肾) excrete(排出) the sodium, calcium is reducing from the bloodstream too.

YOU SHUT SUNLIGHT AWAY

" Vitamin D is required for the body to successfully absorb and use calcium," Dr. Lee says. "Most Americans do not get enough sun exposure to generate enough natural vitamin D, and thus supplementation is essential. " According to the National Osteoporosis Foundation, adults under 50 need 400 to 800 IU of vitamin D daily and adults 50 and older need 800 to 1,000 IU. Talk to your doctor about your specific needs based on where you live, what time of year it is, and which vitamin D-rich foods you eat.

YOU'RE CASUAL WITH WINE

Low levels of alcohol consumption may be good for your bones, according to a study from Oregon State University, but more than a couple of drinks a day has the opposite effect. "Too much alcohol can make it harder to absorb calcium," says Dr. Lee. Furthermore, "In women in particular, higher alcohol consumption can decrease estrogen (雌激素） levels, and this can also lead to osteoporosis(骨质疏松) , " Dr. Lee says.

YOU LIVE IN AN AREA WITH DIRTY AIR

In a study recently published in the Lancet Planetary Health , researchers dealt with hospital data for 9.2 million Medicare participants in the Northeast and mid-Atlantic between 2003 and 2010. They found that even a small increase in levels of pollutants in the air--may lead to an increase in bone fractures and osteoporosis in older adults. If you live in a smoggy area,use an air purifier filter at home, avoid exercising outdoors when the air quality is bad,and get screened for osteoporosis.

Entrepreneur and CEO of Tesla and Space X, Elon Musk may have a little more time on his hands, as he’s leaving his position on the board of the Open AI, according to a blog post.

The departure is likely the result of Tesla’s moving into the field of Artificial Intelligence (AI), which he said in 2017 would be the “best in the world” and would even be able to “predict your destination.” Musk will continue to “donate and advise the organization,” Open AI said in a blog post on Feb. 20, adding that “As Tesla continues to become more focused on AI, this will avoid a potential future conflict for Elon.”

Musk and Y Combiner CEO Sam Altman co-founded the nonprofit enterprise in December 2015, its mission is to develop safe artificial general intelligence and ensure those developments are made public. Open AI researchers published a paper on the site arXiv. org, detailing the possible secure threats that come with “malicious” A I. In fact, Musk has heard of the “evil AI” alarm several times. On Aug. 11, 2017, he warned that artificial intelligence poses a bigger threat to humanity, and he told a gathering of state governors that the government needs to regulate AI before robots start “killing people.”

Musk’s departure from the Open AI board could mean big things for Tesla. As Elon Goodbye, a financial reporter, noted on Futurism, the move “could signal that Tesla is more deeply committed to their own AI projects than we thought.” He added, “Those who have had their ears to any rumors that Tesla is ready to deliver vehicles capable of Level 5 autonomy could take this new Open AI development as a sign that the company is inching closer to that unapproachable goal.” No company has reached that level of autonomy, which means that a driverless car could navigate any road under any conditions and that all the human “driver” would need to do is to input a destination.

1.Why does Elon Musk leave his position?

A. To create safer AI.　　 B. To build the powerful Internet.

C. To develop social communication.　　 D. To avoid a possible conflict with Tesla.

2.What is the Elon Musk’s attitude towards the AI?

A. Ambiguous.　　 B. Negative.

C. Supportive.　　 D. Sympathetic.

3.What does the underlined word “malicious” in Paragraph 3 mean?

A. Advanced.　　 B. Unpopular.

C. Poisonous.　　 D. Traditional.

4.What can we infer from Elon Goodbye’ comments?

A. Level 5 autonomy is impossible.

B. The rumors about Tesla is meaningless.

C. He has no confidence in Open AI.

D. Level 5 autonomy could set human drivers free.
