Some of the conjoined twins are conjoined at the chest. The classical Siamese brothers, everyone knows of them, from the 19th century, they were able to earn a livelihood, and they were able to marry and have a family. They were able to ambulate. They were able to do the most basic human capabilities: walking upright. And the upright walking provides you a three-dimensional perception of space and enhances your motor ability to perform a series of tasks.
They come with a normal brain that receives a constant stimulus from the environment when you are walking upright. And you spread your hands and you go from one point to another point. Those things would have been completely denied to those children.
