Three women were brought to the Singapore General Hospital, each in the same condition and each needing a blood transfusion. The first, a Southeast Asian was given the transfusion but died a few hours later. The second, a South Asian was also given a transfusion but died a few days later. The third, an East Asian, was given a transfusion and survived. That is the X factor in development. Lee Kuan Yew at the University of Singapore, 27 December 1967, as reported by Chandra Muzaffar in his letter to the author, 14 August 1996.
