Liou Seng-Sen and Liou Tang-Sen (1887-?) Siamese Twins Born in China, Tang-Sen (left twin) was stronger and was right handed. Seng-Sen(right) was more susceptible to pain and was left handed. They were also reportedly very intelligent, being fluent in English. It was claimed in 1957 that Hong Kong doctors seperated a 71 year old pair of siamese twins because one was sick. The sick twin died, the other lived. It's unknown whether the story is true, but it is believed that if so it was certainly the Liou brothers, and they are officially the oldest siamese twins ever recorded.
