Background: as part of my job I rent out halls, they are very popular for Asian parties and weddings and my clients are lovely, often bringing me food and inviting me to their celebrations.
Over the past couple of months I've unfortunately had to rent the hall for child funeral meals twice to the same family, the kids were cousins and had the same rare genetic condition. In talking to their grandad he revealed that he and his wife were cousins, then going on to tell me that the parents of the sadly deceased children were also cousins. I looked up that cousin marriage increases genetic conditions 3 fold, the more generations that have practiced it then the higher the probability. With our knowledge of science surely this practice should be outlawed?
