Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.

    Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses（球场） in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.

    There are many environment-friendly sports. Power walking is one of them that you could take up today. You don't need any special equipment except a good pair of shoes; and you don't have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.

    Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be "green gyms". They are better replacements（代替物）for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it's free.

    One day an ant was drinking at a small stream and fell in. She made desperate efforts to reach the side, but made no progress at all. The poor ant almost exhausted was still bravely doing her best when a dove saw her. Moved with pity, the bird threw her a blade of grass, which supported her like a raft, and thus the ant reached the bank again. While she was resting and drying herself in the grass, she heard a man come near. He was walking along barefooted with a gun in his hand. As soon as he saw the dove, he wished to kill it. He would certainly have done so, but the ant bit him in the foot just as he raised his gun to fire. He stopped to see what had bit him, and the dove immediately flew away. It was an animal much weaker and smaller than herself that had saved her life.

    Valentine's Day, a day traditionally reserved for expressing romantic love, is observed practically all around the world. However, not many people are familiar with Sweetest Day. Actually it is a holiday, especially designed to express love and care for those who were routinely neglected（忽视）by society.

Sweetest Day was the idea of Herbert Birch Kingston, who worked for a company in Cleveland, Ohio. He felt that there were plenty of children, especially orphans and poor kids, who didn't necessarily get the attention they deserved. Thus in 1922, he launched the first Sweetest Day to give out boxes of candy to mainly poor children.

    Since the day picked was the third Saturday in October, this became the traditional time to celebrate Sweetest Day. The tradition was so enjoyed that people often looked beyond kindness to treating their own friends or family to treats on Sweetest Day.

    In the US, Sweetest Day is celebrated primarily in the Northeastern region of the US, still on the third Saturday of October. Yet news of the tradition, which began nearly 100 years ago, has spread to other parts of the country, especially as people who lived in those areas moved elsewhere. People may distribute candy or small gifts to those in patient homes, hospitals, foster homes, or mental institutions, and they may also treat friends and family to little gifts from the heart.

    In keeping with the original tradition, celebrating Sweetest Day should really be most focused on people who ordinarily don't have the good fortune of attention from friends or family, either due to difficult family circumstances or to poverty. This can be a great tradition to start if your community doesn't routinely celebrate the day, and there are many candy manufacturers that are willing to help donate or reduce costs on gifts intended for people in unfortunate circumstances.

    India has many festivals, with some celebrations that last for weeks. However, none of them come even close to Holi, India's most colorful and fun festival. Celebrated on the day following the full moon, this year's festival happens to be on March 19th.

    As with most Indian festivals, this one also has many different folk stories. Most of them center around the success of good over evil. The most popular one is about a king, who hates his son Prahlada for loving the creator of the Universe－Lord Vishnu. When every attempt to stop him fails, his sister, Holika believed to be immune (免疫的) to fire, joins in the effort by inviting the young boy to sit with her inside a huge fire. Helped by the power of Lord Vishnu, Prahlada escapes safely, while the evil Holika is burned to death. To remember this event, huge outdoor fires are lit in the night before Holi in order to clean the air of evil spirits and to celebrate the death of the evil.

    So what's so great about this day? While there are some fun parades (游行) and folk songs and dance performances, the most fun of all is walking to the streets and splashing (泼洒) people with water guns and dry colors and even covering them with entire buckets of colored water. On this day, everybody is fair game, no matter how old or how young.

    At about midday, the splashing comes to an end and people living close to oceans or rivers usually take a bath in the water to clean themselves before going home to a delicious home­made big dinner and a well­deserved short sleep, following this full day of fun and activities.

When Lamont Thomas, a retired restaurant employee, became an empty-nester, it was the end of a parenting story. A couple years ago, the divorced father of two became a hero when he took on a kid named Michael Perez in 2001.

"He was a good young man and I just hated to see him in the welfare system," Thomas said.

Thomas eventually adopted Perez, who now works as a nurse.

Perez was just the beginning. Over the next 15 years, Thomas raised more than 30 kids. He did so all as a single parent and with all of his heart.

"Every child that I have had, it was my goal to make a difference in their lives," he said.

When he retired from raising children to spend time fishing and traveling, that didn't last for long.

"It really was a shocker," Perez said. "I didn't expect for him to restart and to do it all over again. "

Thomas began to foster again when he found out that five brothers and sisters all under the age of 6 were going to be permanently broken up. To guarantee they stayed a family, he adopted all of them too.

"I had to help them. They deserved to be raised together," Thomas said.

After Thomas' story first aired, CBS News received a lot of surprising mail from women who expressed interest in the great man. Some notes weren't obvious, others were braver, "Ask Mr. Thomas if he would like a pen pal," wrote one woman, while another said, "I'll marry Lamont!"

But the kids see no room for romance, nor does Thomas.

"I was about to change my phone number," he said.

So he remains single. He spent Thanksgiving with family and is more grateful than ever.
