Passage:
Being young has universal appeal and today people are searching for the qualities that youth comprises good health, mental alertness, physical attractiveness, and vigor—in a word, fitness. Fitness is the magical term that has pervaded our daily lives. Via the media, we are constantly bombarded with suggestions to be slim, do exercise, and feel fit. Many television and radio programs are devoted to fitness information and group exercise. Newspapers and magazines regularly feature columns that present the latest nutritional discoveries and exercise equipment. In fact, it is almost impossible to pick up a general interest magazine and not find the perfect diet and easy exercise programs. Countless books and tapes on fitness are available in bookstores and libraries. The medical profession, too, advocates being slender, doing exercise, and feeling energetic.
The intense interest in the condition and appearance of the body has generated a steady flow of highly marketable innovations. In fact, consumers spend billions of dollars annually on activities and products in their quest for fitness. Health clubs have come into bud throughout the nation, and many people sigh up for lifetime memberships. Others, who prefer convenience and privacy, set up fitness equipment in their own homes. Many people shop in health food stores for organically growth goods and dietary supplements to add extra vitamins to their diets.
For many years, it has been the practice of giant corporations to maintain a gym or health club for the exclusive use of their executives. By working out at the gym, or playing tennis, the top people in management could release some of the tensions generated at work. Membership in these corporate facilities was, and still is, a status symbol. Currently, however, a new attitude is emerging. All employees are burdened with tensions and pressures and could benefit from this type of recreation. As a matter of fact, studies contributes is also a financial gain for the company. It therefore is sensible of those major corporations to offer health club memberships to all their employees. This concept is revolutionary, but it is being considered seriously. There is no doubt about it: when people are physically fit, they are at their best. It makes sense to maintain optimum health in order to live life to the fullest.

年輕具有普遍吸引力，今天人們在搜尋著構成年輕的要素：好的身體，精力充沛、身體的外在魅力，朝氣蓬勃——一句話，健康。健康這個富有魔力的術語在我們日常生活中蔓延開來。通常媒體，我們不斷地被各種各樣的建議所包圍，諸如要保持苗條、要鍛鍊身體、還要保持好的精神狀態等等。許多電視和廣播節目致力於向人們提供健身資訊和群體健身活動。報紙和雜誌也闢有特色專欄，向人們呈現關於營養的最新發現和健身裝置。實際上，隨便拿起哪本大眾雜誌，都可以找到關於完美飲食和簡易健身的專案。書店和圖書館裡隨處可見無數有關健康的書籍和磁帶。醫學行業也倡導人們保持苗條身材、加強身體鍛鍊、保持精力充沛。
對身體狀況和外在形體的廣泛關注，導致高度市場化的創新穩步發展。事實上，消費者為健身活動和產品每年都要支出數十億美元。健康俱樂部如雨後春筍遍佈全國，許多人都註冊成為終生會員。那些喜歡方便和隱私的人則自家購置了健身器材。許多人在保健品店購買有機產品和膳食補充劑來額外補充維生素。
多年以來，大型公司為企業高層管理人員配備專用健身房和健康俱樂部。通過健身房的鍛鍊，或者打網球，高階管理人員可以釋放工作中的壓力。擁有這樣的會員身份，至今仍是一種身份地位的象徵。然而，目前又出現了一種新的趨勢。公司所有員工都揹負沉重的工作壓力和緊張，因此都可以享受這種娛樂活動。實際上，研究顯示，身體和精神健康可以切實幫助員工提高工作效率。病假時間減少也是公司的一項財政收入。因此，那些大公司向全體員工提供健康俱樂部會員身份是很明智的決策。這種理念是革命性的，但是需要認真給予考慮。毫無疑問的是：當人們身體健康的時候，其工作狀態也處於最高峰。為了能夠更充實地生活，保持身體處於最佳狀況是非常有意義的一件事情。
