More and more Chinese are jogging to get and stay fit. Most joggers will run alone, but some will jog with friends or even coaches. The Beijing Olympic Forest Park is one of the most popular spots. It is packed with runners in the afternoon, usually after work, and at weekends. Jogging after a whole day39。s smoggy days. If the smog is severe, I39。ll wear a mask, or just ignore the smog and go on jogging, she said. For those who are not so athletic, jogging also has its attractions. Wu Houbin started roughly two years ago, when he was severely obese. Within two months, his weight dropped from 82 kilograms to 64 kilograms. The success helped him recover health, and he has made friends. Jogging does not require speed, but stamina. If you want to stick to the game, you need to take it as a mission, a habit, and then eventually a hobby, Wu said. But persevering with jogging is not always easy. Jogging is beneficial for heartlung function, and the skeletal system, but doctors say improper technique damages the joints, especially the knees and ankles. Excessive jogging wears down the body, and harms one39。s Pink Revolution, an annual campaign that seeks to raise awareness and funds for breast cancer research, the hotel recently announced. A major sponsor of the campaign for three years in a row, Conrad Macao has pledged to donate a portion of its proceeds to the fund, includ ing those collected from selling its popular bear and rubber duck merchandise, in limited pink editions. Pink is the theme for floral arrangements and decorations in the hotel in October. In addition, on Fridays that month, members of the management and staff will add something pink to their uniforms, regular s and handwritten guest cards. Breast cancer is the mos
