Her body may be ready for children, but her heart is not.So said Hong Kong singer Joey Yung in a phone interview with The New Paper last month to promote her gig here.The 32-year-old sees a traditional Chinese medicine physician to ensure she stays healthy ahead of a series of concerts in Hong Kong in December."I fell ill quite often last year and at one point even lost my voice. So this year, my biggest wish is to remain healthy," she said in Mandarin.Yung said she has been given a clean bill of health by her doctor."He even told me my uterus is fine,and I can be a mother anytime. But I told him I don't want to have kids yet, I just want to be in good health."Yung, who is dating Hong Kong singer Wilfred Lau, 36, said she wants to focus on her career."I probably won't even think about settling down or having children for the next three or four years," she said."If I start a family, it will affect my work, and because of that, I'll feel that I'm being irresponsible."For nearly a decade, Yung's sexual orientation was the subject of much speculation, as she had been romantically linked to singer Denise Ho since 2002.Neither of them addressed the rumours, but last June, Yung revealed she was dating Lau. However, when asked if Lau agreed to not starting a family just yet, Yung, sidestepped the question.She said: "Communication is very important in any relationship. We talk about nearly everything, so I can't really remember if we discussed this topic before.
