1 . Take a look at your fingers. Would you believe me if I told you that the length of your fingers in relation to one another can predict your personality? I know that it sounds like one of those silly tests you see on Facebook, but I have to admit that it was spot-on for me.

Look at your three middle fingers of your left hand. Is your index finger(食指)longer than your ring finger? Is your ring finger longer than your index finger? Or are the two the same length?

Category 1: A longer ring finger. If your ring finger is longer than your index finger, research shows that you’re likely a charming type, and you can probably talk yourself out of any situation. Others often find this personality type irresistible(无法抵制的)and will go to great lengths to help you. You’re more likely to take risks, and you’re good at problem-solving. People in this category make great engineers, soldiers and crossword-puzzle solvers.

Category 2: A longer index finger. If your index finger is longer than your ring finger, chances are that you are full of confidence — possibly even to the point of being over-confident and too proud. You are not necessarily shy, but you do enjoy time to yourself especially when you’re trying to complete a project. You are a determined go-getter who can make things happen, but you may be shy when it comes to taking the first step in building up a friendship. You are also probably happy with what you have, but you’re always wishing for more.

Category 3: The two are the same length. If your index finger and ring finger are roughly the same length, you are likely to avoid conflict at all costs and seek to keep the peace in your relationships. You are well-organized, faithful and sympathetic. But deep down under all of that caring and peace-loving, you also can go mad unexpectedly when you’re pushed too far.

How well did these descriptions match your personality? I was surprised at the accuracy in my case.

4 . Mark Bertram, 46, lost the tips of two fingers at work in 2018 when his hand became trapped in a fan belt. “It's life-changing but it's not life-ending,” he says. “Doing work is harder now. Everything is just a little different.”

After two surgeries and occupational therapy, Bertram decided to make light of his condition by asking Eric Catalano, a tattoo (纹身) artist, to create fingernail tattoos. The idea made everyone in the studio laugh—until they saw the final result. “The mood changed,” Catalano recalls from his Eternal Ink Tattoo Studio. “Everything turned from funny to wow.”

When Catalano posted a photo of the tattoos, a pair of fingernails that looked so real that no one could believe their eyes, he had no idea the image would eventually be viewed by millions of people around the world.

The viral photo pushed Catalano, 40, further into the world of paramedical (辅助医疗的) tattooing. Now people with life-altering scars come from as far away as Ireland to visit his shop. They enter Eternal Ink looking for the artistic healing they saw online. Using flesh-toned (肉色的) inks and a needle, Catalano transforms his clients' view of themselves.

Leslie Pollan, 32, a dog breeder in Oxford, was bitten on the face by a puppy in 2014. She underwent countless surgeries to correct a scar on her lip.

“Plastic surgery gave me no hope,” she says. “So I looked for other options.” She ultimately traveled six hours to meet with Catalano. He hid Pollan's lip scar, giving her back a piece of her confidence.“ You don't understand until you've been through it,” Pollan says. “It made me have a different look on life.”

Catalano performs up to eight reconstructive tattoos. While he charges $100 per regular tattoo, he doesn't charge for paramedical tattoos. “Financially, it doesn't make sense,” Catalano says. “But every time I see that emotion from my customers, I'm 100 percent sure this is something that I can't stop doing.”

6 . Losing a baby tooth can be fun for a kid. You can put it under your pillow and look forward to finding some money there in the morning. And then you can watch your new permanent(永恒的）tooth grow in its place.

But if a permanent tooth falls out, that's a problem. There isn't another one under the gum（齿龈）that can replace it. Unfortunately, this happens to some older people. And if permanent teeth fall out or need to be pulled, an older person might need dentures.

Dentures,known as false teeth, are a set of replacement teeth for any teeth that are missing.

There are partial dentures, which take the place of only a few teeth and prevent the others from changing position. If all the teeth are gone, the person would need complete dentures,which replace every tooth in the mouth.

Dentures can cause pains at first but take little time to get used to.They also need special care. They should be brushed daily with a special denture brush and cleanser and soaked(浸泡） in denture solution when not in the mouth.

Dentures are important for the old because, without teeth, it's hard to smile, talk, and eat properly. But it can be a little weird if you see someone take out his or her dentures. It can also be strange to see someone, like a grandparent, without dentures in because he or she won't have any teeth. Try not to make fun of the person because this could cause hurt feelings.

People usually lose their permanent teeth due to periodontal disease (牙周炎）， or gum disease, which is caused by bacteria that attack the gums. Diseased gums aren't strong and healthy, so teeth can get loose and fall out. Older people often have many cavities (洞） that have been filled over the years, and these fillings can weaken over time, leading to more tooth problems.

7 . Things Could Happen If You Keep Rubbing Your Eyes

Rubbing eyes can often result in significant damage, from causing eye disease to making existing conditions worse and increasing your risk of infection. Here are things that can happen if you keep rubbing your eyes.

People who are nearsighted may find that rubbing eyes results in worse eyesight. Nearly 9.6 million people are what is known as highly nearsighted and their eyes degraded over time, according to research from the American Academy of Ophthalmology.

    2    they can still pick up thousands of germs every day. Touching your eyes with your hands, especially when you never wash your hands can transfer bacteria that can cause eye disease, for example, pink eye, according to the American Optometric Association.    3    , a warm press may help calm it. Don't miss these easy ways to improve your vision.

    4    It may also make the eyelid lose flexibility over time. That's a less serious problem, but still not something we want to happen. Is there any safe amount of rubbing your eyes？It is recommended that you apply the same amount of pressure to your eyes that you would if you are drying your face with a towel.

If you rub your eyes hard enough, you might cause tiny blood vessels in your eyes to break. That could result in bloodshot eyes. The blood will then flow to surrounding tissue.    5    

8 . Hair Loss (Alopecia)

Information about male pattern baldness(秃顶) causes, triggers and treatment in the UK

In contrary to popular belief, hair loss—or alopecia—can start at any age. While it is associated with mature males, and statistics show it does mainly affect men above 40, the reality is you can notice symptoms in your 30s, or even 20s and teen years. The NHS statistics state that 25% of men start losing their hair by the time they reach 30. The most common form of hair loss is male pattern baldness—also known as androgenic alopecia—that affects more than half of men around the world.

One option many men seek is treatment to avoid further hair loss, especially early on in the process. With treatments, such as Propecia, that specifically target male pattern baldness, it is possible to stop hair loss completely and even encourage fresh new hair growth.

What is alopecia?

Alopecia is the medical term for hair loss. Most commonly affecting males, hair loss in men is caused by an increased sensitivity to the male sex hormones (androgens). The type of alopecia you have (as well as hereditary and external factors) can influence levels of hair loss. The most common type of hair loss (alopecia) is male and female pattern baldness. Other types include：

* Alopecia areata (patches of baldness, usually on the scalp)

* Scarring alopecia (hair loss directly affecting the hair follicles)

* Telogen effluvium (hair thinning over a larger area on the top of the head, rather than bald patches)

* Anagen effluvium(most commonly caused by cancer treatments such as chemotherapy and radiotherapy)

9 . How to Strengthen Teeth Naturally

    1    You can work on strengthening your teeth by getting the right vitamins and minerals in your diet. You can also protect your teeth through healthy habits. In addition, avoiding certain foods and habits can help strengthen your teeth.

◆Get the right nutrients(营养)

Make sure you’re getting 1,000 to 1,200 mg of calcium(钙) a day. You probably know calcium helps keep your bones strong.     2    Eating certain amount of calcium in your diet every day will help increase the strength of your teeth.

◆     3    

Aim to eat a wide variety of fruits and vegetables in your weekly diet. Try selecting a variety of colors when choosing your produce, as that ensures you’ll be getting a wide variety of vitamins. Fill your plate up halfway with fruits and vegetables at every meal, then fill the rest of your plate with some protein and whole grains.

◆Brush your teeth twice a day

To brush well, hold your toothbrush at a 45℃ angle to your teeth. Brush all the surfaces of your teeth gently and try to brush for at least 2 minutes.     4    

◆Visit your dentist regularly

Visit your dentist at least once a year for x-rays and cleaning.     5    If you start to get a buildup of plaque(牙菌斑), which can weaken teeth, the dentist can remove it for you in time.

◆Quit smoking

You probably are aware that smoking causes lung cancer and other health problems. In addition, it can also weaken bone tissue, including your teeth. If you’ve been thinking about quitting, now may be the time.

10 . Researchers at Brigham found about one in five teenagers now have some degree of hearing damage. The researchers did not say why hearing loss has risen, but other experts have strong suspicions. One likely culprit, they say, is MP3 players.

An MP3 player can be dangerous to hearing when its decibel level is turned up too high. High-decibel sounds can damage nerve endings, called hair cells. If a sound is loud enough, the damage can be permanent. A loud sound can shake the membrane (薄膜) on which the hair cells sit- “like an earthquake”. That shake can break or even uproot hair cells. When that happens, the hair cells are finished. Human ears cannot regrow hair cells. Therefore, when listening to an MP3 player, set a volume limit and avoid exposure to loud sounds.

On the other hand, the loudness of today’s music may not be totally under your control. Music companies have been purposely turning up the volume. It’s a trend called the fight for loudness.

Play a CD from the 1990s. Then play a newly released tune. Don’t touch the volume control. You’ll probably notice that the new CD sounds louder than the old one. Why? Sound engineers who create CDs are using dynamic range compression (压缩), a technology that makes the quiet parts of a song louder and the loud parts quieter. The overall effect of compression is a louder recording.

Many musicians and sound engineers aren’t pleased. They say that compression is driving down the quality of today, s music, making it sound flat and blaring. Gray Hobish, a sound engineer, explains that music should be a combination of loudness and softness. But music companies want to make music louder so it will stand out. That’s important in the competition among recording companies.

What about listeners? Many teenagers listen to music on the go in noisy places and through headphones, all of which reduce sound quality. So young listeners may not notice the poorer quality of modem recordings. “To their ears,” says Hobish, “the music sounds fine. And they are not aware of the hidden threat of the music they are enjoying.”
