Knowing which of these statements have been proved by SCIENCE - and which are MYTHS(谬论) - could improve your health. Here are some health facts your doctor wants you to know.

Not all heart attacks have a symptom(症状) of chest pain.

Truth! A 2012 study of more than 1.1 million heart attack patients found that 31 percent of men and 42 percent of women didn't have any chest pain before being hospitalized. Call 911 for other symptoms, too, including shortness of breath, light - headedness, and pain elsewhere in the upper body.

You do not need eight glasses of water every day.

Truth! There is not any scientific evidence that eight is the magic number. You might need more or less than that, depending on factors(因素) such as climate and body size. To make sure you are getting enough, just drink water throughout the day.

You need less sleep as you get older.

Myth! Older adults often sleep less as a result of serious conditions that are more common with age as well as the drugs used to treat them. But that doesn't mean they require less sleep. While sleep needs vary from person to person, most adults should get at least seven hours of sleep for health.

Reading in dim(昏暗的) light will harm your eyes.

Myth! It might tire your eyes in the short term, but there's no evidence that it will do any lasting damage. When reading, position light to shine directly on the page rather than from over your shoulder to reduce unpleasant bright light.

A Portland, Oregon man, Colin O' Brady, has become the first person to travel across Antarctica by himself with receiving any assistance.

O' Brady completed the 1,500 - kilometer trip on Wednesday. He crossed the continent in 54 days. Friends, family and other people followed his progress through messages and pictures he left on social media. The 33 - year - old O' Brady documented the trip on the social networking service Instagram.

He wrote Wednesday that he traveled the last 129 kilometers in one big, final push to the finish line. The distance took over one day to complete. O' Brady wrote, "While the last 32 hours were some of the most challenging hours of my life, they have quite honestly been some of the best moments I have ever experienced."

The day before, he wrote that he was "in the zone" and thought he could make it to the end without stopping. "I'm listening to my body and taking care of the details to keep myself safe," he wrote "I called home and talked to my mom, sister and wife - I promised them I will stop when I need to."

Other people have traveled across Antarctica, but they all had some form of assistance. They either had better, more plentiful supplies or equipment that helped move them forward. In 2016, British explorer Henry Worsley's died in his attempt to travel alone across Antarctica unassisted. Worsley's friend Louis Rudd, also from Britain, is now attempting an unaided solo(单独的) journey in honor of Worsley. He was competing against O' Brady to be the first to do it. O' Brady plans to stay on Antarctica until Rudd finishes his trip.
