There's no doubt that man is the smartest. But do you know what other animals are smart, too?

Dolphins

    Dolphins are very smart. Most of the “tricks” they're taught to do are actually behavior they would engage in on their own. They love to play, race and generally enjoy their life to the fullest. They speak a language we have yet to completely understand and like all civilized creatures, dolphins' mothers always provide their young children with guidance and possibly, love.

Great apes

    The great ape family primarily consists of gorillas, chimpanzees and orangutans. Their brain chemistry is so similar to humans' that NASA once used chimpanzees in place of astronauts during many dangerous missions. Gorillas have been taught sign language and orangutans exist in complex familial relationships.

Elephants

    Everyone has heard the phrase “an elephant never forgets”. Elephants establish long-term friendships, recognizing and remembering their friends years later. If an elephant comes upon a fallen friend, it has even been known to feel sad.

Parrots

    As proved by this list, parrots are very smart. They are also the only animals listed that can actually hold a conversation. Some parrots know hundreds of words by imitating humans. The birds are also capable of remembering words and using them intelligently in response to situations.

    Last week I was riding my special motorbike and then stopped at a convenience store.As I was getting my wheelchair off the back,a man watched me from his car and I noticed a wheelchair in his back seat.We spoke for a moment and I asked him about the wheelchair.He answered that it was for his daughter.“Well,do you think she would like to go for a ride on my motorbike with me?”I asked.He seemed shocked that a total stranger would ask him this.He thought about it for a second and said,“OK,as long as I can follow you.”

    He introduced me to Amy and he sat her on my back seat.Her father followed me for a few miles and she talked non-stop about what she wanted for Christmas.

    As we came back to the convenience store,she said,“This ride is the best Christmas present I could ever receive. I have been in a wheelchair my whole life and didn't know I could do this.”I told her about some of the other things I do (ski,travel the world by myself,etc.).As her father was taking her off my bike,she turned to him and said,“Oh Daddy,I'm going to be OK.Mr.Bryant does all kinds of things,and I win too.” Her father turned away as a tear of joy rolled down his cheek.He hugged me and said,“I was sitting here praying for a gift for Amy that would encourage her.She often felt that her life was dull compared to other children.God answered my prayer just now.Now I pray that God will bless you for your gift to Amy today.” I believed what he said.Being kind and thoughtful to others,we can be an answer to prayer.

    A family is a collection of people who share the same genes（基因）but cannot agree on a place to pull over for lunch. Ed and I, plus his parents and sister Doris and eight-year-old niece Alisha, are on a road trip to Yosemite. Ed wants Subway, I want. In-N-Out Burger, Doris wants Sonic. In the end, we compromise on McDonald's, where Alisha will get an action figure.

    It's a three-hour drive to Yosemite, but we're taking a little longer, as we're working in a tour of Highway 80's public restrooms. As the saying goes, “Not one bladder（膀胱）empties but another fills.” Many of these restrooms belong to gas stations. I prefer them to the high-tech ones on planes.

    We get back on the road. Ed is driving now. When all the tabloids（小报）have been read, the travel has grown tedious and anyone under age 12 asks “Are we there yet?” at ever-shortening internals. Just outside Manteca, California, we stop for coffee. At a Starbucks checkout, Ed buys a CD of Joni Mitchell's favorite musical picks. The hope is that it will have a calming effect.

    As we pull back onto the highway, it starts to pour. Then something amazing happens. As we climb the mountain, the rain turns to snow. The pines are spotted with white. We're struck dumb（说不出话）by the scene outside. For a solid 15 minutes, everyone forgets about their bladder, their blood sugar and the temperature. Alisha has never seen snow, so we pull over to make snowmen and catch snowflakes on our tongues. Then Ed realizes we need tire chains, and we have to turn back and drive 30miles to Oakhurst. “Good,” says Doris. “There was a very nice restroom there.”

Hair Loss (Alopecia)

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

    In contrary to popular belief, hair loss­or alopecia­can 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 baldness­also known as androgenic alopecia­that 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)

    Move over, helicopter parents. "Snowplow(扫雪机) parents" are the newest reflection of an intensive(强化的) parenting style that can include parents booking their adult children haircuts, texting their college kids to wake them up so they don't sleep through a test, and even calling their kids' employers.

    Helicopter parenting, the practice of wandering anxiously near one's children, monitoring their every activity, is so 20th century. Some rich mothers and fathers now are more like snowplows: machines moving ahead, clearing any difficulties in their children's path to success, so they don't have to suffer failure, frustration(挫折)or lose opportunities.

    It starts early, when parents get on wait lists for excellent preschools before their babies are born and try to make sure their kids never do anything that may frustrate them. It gets more intense when school starts: running forgotten homework to school or calling a coach to request that their children make the team.

    Rich parents may have more time and money to devote to making sure their children don't ever meet with failure, but it's not only rich parents practicing snowplow parenting. This intensive parenting has become the most welcome way to raise children, regardless of income, education, or race.

    Yes it's a parent's job to support the children, and to use their adult wisdom to prepare for the future when their children aren't mature enough to do so. That's why parents hide certain toys from babies to avoid getting angry or take away a teenager's car keys until he finishes his college applications.

    But snowplow parents can take it too far, some experts say. If children have never faced a difficulty, what happens when they get into the real world?

    "Solving problems, taking risks and overcoming frustration are key life skills," many child development experts say, "and if parents don't let their children experience failure, the children don't acquire them."

    Cao Zhawa has been planting trees for most of his life. He lives and works in the heart of Mu Us Sandyland, an area in the southwest part of Inner Mongolia.

    In 1958, when he was just 16 years old, Cao started planting trees. Cao's trees now cover an area of more than 1.3 million square meters. Cao's forest is worth an estimated 10 million yuan and can produce 100,000 kilograms oxygen, enough to sustain a full-grown adult for nearly a year.

    Mu Us Sandyland is one of the places in China most affected by erosion(侵蚀) and desertification. The amount of annual rainfall ranges from 150 to 300 millimeters, while evaporation(蒸发) between 2,000 and 3,000 millimeters. Cao recalls that his growing-up was troubled by sandstorms. This was one of the factors that motivated Cao to join and stay on the tree-planting program.

    Popularly known as the "Green Great Wall", the project, which is set for completion in 2050, would be a 4, 800-kilometer greenbelt of trees and shrubs(灌木) protecting the area from strong winds and preventing soil erosion. Since the start of the Three-North Shelter Forest Program, millions of people have joined in and become a vital part of the plan.

    However, the tree-planters face a host of challenges, with watering the most difficult among them. "When I was young, the level of groundwater was high," said Cao, "But with less rain, the trees are hard to plant and keep alive."

    Planting trees has also become harder for Cao as he ages. However, he doesn't want to leave the forest in the care of his children, and he insists the land belongs to the government. "When I die, I just want to be buried under the trees," Cao said. "Then I will be with them forever."
