Five things we're all wondering about 1 Hong Kong's first sperm bank to close ... we're wondering how the government's Deposit Protection Scheme will deal with this? 2 Magistrate rules chief executive has too much power over airwaves ... so Donald Tsang Yam-kuen is the guy to lobby if we want 'less talk, more rock' on radio. 3 Public toilets planned for three MTR stations ... but they'll make every effort to make all other stations smell like one. 4 Study says too much ocean fish is harmful to children ... where was this study when mum tried to force-feed me spoonfuls of cod liver oil? 5 The Western Harbour Tunnel increases tolls again ... it's so expensive now they are going to have to change its name to the Louis Vuitton tunnel.
