South Korean hip-hop girl band 2NE1's hit single I Don't Care is blaring on the radio of the golf buggy taking a group of lazy journalists the short distance from the media village to the main press centre. It is catchy and I try to move to the music, much to the amusement of the volunteer driving the cart and the other journos on board. It's early in the morning and what better way to get into the swing of things than to listen to Park Bom. Her free-spirited lyrics, however, would not go down well in a country where the controversial one-child policy is very much in effect in urban areas. They care very much and this is why condoms are aggressively marketed and freely available everywhere. Even the Games organisers have got into the act, providing free condoms to all athletes and officials. Jissbon, the official donor to the Games, has come up with a special edition of Asian Games condoms with the packets cleverly named. One urges users to 'don't peak too early' while another boasts of 'flawless entry'. I don't know about the one which says 'it's a team sport'. I wonder what the women's cricket team who have already returned to Hong Kong, or the men's hockey team who have been royally hammered to the tune of 19 goals by India and Pakistan, thought about that. China didn't always have a one-child policy. In the 1960s and '70s, many parents had large families. Shirley, one of the first volunteers I met, comes from a large family by current standards. She has two elder sisters and a younger brother. She is happy. That is not the case with Blair, a reporter with the Southern Metropolitan newspaper in Guangzhou. She is the only child and says she yearns for company. During Chairman Mao's rule, from 1949 to 1976, having more children was regarded as good. The little red book extolled those values, for Mao felt having a large population would turn China into a great power. He was right. Today China has more than 1.3 billion people, making it the world's most populous country. It accounts for 20 per cent of the global population of roughly 6.7 billion. These numbers have also translated into economic might. With Mao's death in 1976, China took a new tack with his successor, Deng Xiaoping, deciding that maybe the people should spend more time out in the fields than in the bedroom. In September 1980, the Communist Party told its members to lead the way and set a glowing example by having just one child. That was the start of the one-child policy. This is strictly enforced in cities but is more relaxed out in the boondocks. It is estimated this policy has helped restrict the population by anything between 250 million and 400 million people. Less people mean fewer resources are needed to feed, clothe, educate and house them. That is the official line. But others say the decline has nothing to do with placing restrictions on a husband and wife, but it is more about Mother Nature taking its own course with a drop in fertility rates. It seems most Chinese men are grappling with a problem - falling sperm density. The China Daily this week said 80 per cent of men failed an initial sperm bank test. But the bar has been set high. Licensed sperm bank clinics in China require sperm density of 60 million little swimmers per millilitre, which is three times that of the 'average healthy male' as defined by the World Health Organisation. There is apparently a huge waiting list at these banks, simply because deposits or donors are few. Once the confusion over what happens at the sperm bank had been cleared - the banks used to receive calls from prospective donors who wanted to know 'if the nurses give a helping hand' - very few people turn up because of the lengthy process involving a number of tests which can take more than 10 months. Yet, the need is huge because of falling fertility rates, according to the mainland newspaper. In time, maybe, the one-child policy might become outdated. An ageing population might force Chinese authorities into a rethink. Soon condom manufacturers might run out of business. But for now it is boom-boom time in Guangzhou, especially that packet which begs athletes to 'go for gold'. And everyone is at these Games. To test the organiser's efficiency, one Hong Kong team official hid the packets supplied. 'The next day we had more packets in our room. It was replenished,' said the official, who wished to remain anonymous.
