Here is an astonishing and significant fact: Mental work alone can't make us tired. It sounds absurd. But years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue (tiredness). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day laborer, we would find it full of fatigue toxins (毒素) and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.

So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?   

Some scientists declare that most of our fatigue comes from our mental and emotional attitudes. One of England's most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare.” Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”

    What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated—those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.

                                                                                      The Lifecycle of a T-shirt

    We all probably have a lot of T-shirts, but do you ever stop and think about the influence of a T-shirt on the planet? You'd probably be surprised to learn what's involved in the lifecycle of just one T-shirt.

    There are 5 major stages: material, production, shipping, use and disposal. The material stage involves farming, irrigating, fertilizing, harvesting and ginning. While cotton is a natural fiber (纤维) and not as harmful to the environment as manmade fibers, it still takes a toll in the material and production stages. Commercial cotton farming uses a large amount of water, and the use of pesticides (杀虫剂) is widespread across the globe, especially in cotton farming. Studies have shown that farmers spend around $4.1 billion on pesticides annually, of which 25% was spent on cotton crops in the US.

    Once the cotton is grown and harvested, so begins the production stage: spinning, knitting, bleaching, dyeing, cutting, sewing, etc.——these processes also use a great deal of water and energy. Commercial dyes and bleaches are harmful pollutants and can eventually pollute groundwater.

    After the T-shirt is produced, it enters the transportation stage. This often involves overseas shipping. Take a look in your closet. Chances are that most of your cotton garments (衣服) are made in China or India. Garments can be shipped via plane, ship or truck…, all of which spill CO₂ into the atmosphere. Calculations show that CO₂ emissions from light trucks alone amount to 1.15 pounds per mile.

    Once the T-shirt reaches the retail market, it is purchased. This stage may seem like the leastenvironmentally damaging part. But consider the number of times you've washed and dried your favorite T-shirt. Washing machines are certainly becoming more efficient. However, the average American household does 400 loads of laundry per year, using about 40 gallons of water per load. Such excessive water use is combined with the large amount of energy used by dryers.

    The final stage of life is disposal. This releases harmful emissions, or involves a landfill where cotton takes years to break down. Current US records show that an estimated 15% of clothes and shoes are recycled, which means that consumers send a shocking 85% of these materials to landfills.

    We all need new clothes every once in a while, but let's all try to keep in mind what goes into the production of clothing... It has a real impact on the planet.

    There are a lot of things you can do to help reduce your impact. Reuse and recycle clothes. If they're too worn out to wear, cut them up and use them as cleaning rags. Donate them to charity or another organization that recycles textiles. When possible, make an effort to buy organic cotton. Turn down the thermostat on your washer, and line dry your clothes when the weather will allow it.

    One evening at a busy crossroads, I noticed a sister struggling to keep her little kid under control while she talked on the pay phone. She wanted him to stay still next to her, but he wanted to run and play by the road, close to rushing buses and taxis. One could sense the woman's frustration, that she was pulled in too many directions: She was angry at the person on the telephone and shouting at the younger that she would “snap（折断）his leg” if he moved again. As I waited for the traffic light to change, the child began to complain and struggle to free himself from the woman's grasp. She dropped the phone, seized（抓住）the neck of his tiny. T-shirt and gave him a back-hand blow across the face that I know made his little head spin.

    The light changed, and passers-by continued on their way. But I stood there, fixed to the pavement. I knew this extremely upset woman would carry through on her threat of violence to the child. Before, I had wanted to get close to her and offer to watch the youngster while she dealt with the troubling situation on the phone. Now I wanted to comfort the little boy. I also wanted to speak to the sister to calm her and to caution（告诫）her, as I wish someone had cautioned me when I was passing my pain on to my daughter and causing her emotional suffering. But I was chicken. I thought, she may think I'm out of line, or I may be her next target.

    Often I've thought about that child and the many others abused（虐待）by adults. I wonder how they will internalize（使……藏在心底）their pain, and if it will crush their spirits. Will this little boy grow up to be an abusive man? Will he be gloomy（阴郁的，沮丧的）and withdrawn（孤僻，内向的）? Will he find it hard to communicate with women, with other men? Or will he survive and be sensitive, caring and determined not to continue the cycle?

    There is too much cruelty（残忍）in the world, too much cruelty between people. I tremble at the increasing verbal（言语的）bitterness and violence among Black girls, and among young mothers trying to discipline their children. This behavior isn't class-or age-related: I hear sharp words from Black women from all walks of life who are overworked and stressed out and have grown impatient. At times I, too, become impolite to others, or, like the sister on the phone, strike out at（抨击）those closest to me.

    Often we're tired because we've made the wrong choices. Young girls who still need mothering are loaded with children. We sisters easily get hurt and annoyed when we don't compromise with our own sense of self. Our personal fulfillment requires knowing what is best for us, setting our boundaries（界限）and keeping them undamaged. We will always be asked to do more than we are comfortable doing. When we know our boundaries, we can decline comfortably. People—and we ourselves—will act in ways we don't like. But they, like us, are still worthy of love.

    Whatever irritates（激怒）us about a person should be examined. Is the person reflecting behavior in us that needs to be changed? Often, when I find people irritating, I find they mirror something about me that I need to correct.

    What's needed in our personal relationships is a return to gentleness and tolerance（容忍）. We must allow one another our learning experiences. Just as violence results to violence, verbal violence—the hard words and sharp tones we use to release inner stress—adds to the distance between us.

    What we people of African root must do to become, and continue to be strong begins with love, sensitivity and our ability to work together. We Black women have these spiritual resources in abundance（丰富）. Now we must encourage them to create a peaceful place—for ourselves, our children, our men.

    Everybody, at some point in their lives, has experienced failure. It could be something as simple as not getting the job you wanted, or getting fewer marks even after hard work. But what makes you is not your failure, but how you get back up after being hit.

    Once, a young school boy was caught in a fire accident in his school and was assumed that he would not live. His mother was told that he was sure to die, for the terrible fire had destroyed the lower half of his body. Even if he were to survive, he would be lame throughout his life.

    But the brave boy did not want to die nor did he want to be lame.  Much to the amazement of the doctor, he did survive. But unfortunately from his waist down, he had no motor ability. His thin legs just hung there, lifeless. Eventually he left the hospital. But his determination to walk was unshakable. At home, when he was not in bed, he had to stay in a wheelchair. One day, he threw himself from the chair and pulled himself across the grass, dragging his legs behind him. He reached the fence, raised himself up and then began dragging himself along the fence, firmly determined. He did this every day, with faith in himself that he would be able to walk unaided. With his iron determination, he did develop the ability to stand up, then to walk on and off, then to walk by himself and then to run.

    He began to walk to school, and then run to school, to run for the joy of running. Later in college he was on the track team.

    In February 1934, in New York City's Madison Square Garden, this young man who was not expected to survive, who would surely never walk, who could never hope to run-this determined young man, Dr. Glenn Cunningham, ran the world's fastest mile.

    A good example of the power of positive thinking and faith in one's self, Glenn Cunningham continues to be an inspiration for many, and his story, a brilliant evidence to how one can bounce back even when all difficulties are piled against one, to the degree that death seemed the preferable option.
