在近来一段日子里,许多电视台铺天盖地的播放着这样一则广告:“爸妈今年不收礼,收礼只收脑白金”。如此奥秘的脑白金究竟为何物?据说,脑白金是一种能防止老化、预防心脏病、推迟更年期而保持青春活力的灵丹妙药。据广告宣传,脑白金的发现首先使美国人疯狂。5000万人疯狂抢购,一粒含量仅3毫克的脑白金在加州被炒到50美元,是饰品白金的1026倍。日本为它沸腾,台湾和香港亦为它痴迷,有人预言中国内地将掀起更大的狂热。世上真有如此神奇的保健品吗? In recent days, many television broadcasters have been broadcasting such an advertisement: “My parents do not receive gifts this year and receive only melatonin.” It is said that melatonin is said to be a miracle cure to prevent aging, prevent heart disease, postpone menopause and maintain youthful vigor. According to advertising, the discovery of melatonin first made Americans crazy. 50 million people crazy buying, a content of only 3 mg of melatonin in California was fired to 50 US dollars, is 1026 times the platinum jewelry. Japan is boiling on it, and Taiwan and Hong Kong are also obsessed with it. Some people predict that the mainland of China will set off greater fanaticism. Is there such a wonderful health care product in the world?
