Not only do the Lim twins Xin Shan and Xin Xiang look identical, they also appear to be inseparable.
The 30-year-olds attended the same schools for nearly 20 years, including all six years as classmates at Xinmin Primary School. The brothers also spent two years at Nanyang Junior College and another eight years as coursemates - first as undergraduates and later as doctoral students - at the National University of Singapore (NUS).
