However, the two James were different. They were separated from one another and adopted by different families, called Lewis and Springer, a few weeks after they were born and they did not meet until after 39 years.

　　 When the scientists at Minnesota learnt about the two James, they were naturally invited to come to the University, where investigations revealed the most astonishing similarities about their lives:

　　 * Both married girls called Linds, were divorced and then married women called, Betty.

　　 * Both owned dogs called Toy when they were boys.

　　 * Both had worked for the hamburger chain, McDonald's, and at filling station.

　　 * Both had the habit of biting their fingernails.

　　 * Both have similar sleeping problems.

　　 How can one attempt to explain so many coincidences? Is it possible that twins have some mysterious way of communicating? Or does our gene make us take particular decisions in certain circumstances? In any case, it seems that many more aspects of our behavior are influenced by genetic factors than we had previously imagined.
