Life is full of unbelievable things and the story of the Jim twins is just one of them. What are the chances of them marrying women with the same name (twice!) and naming their sons identically, given that they have never met each other ? Their unusual story only comes to show that genes are stronger than most other factors forming personality such as family, education, friends, etc. And yet, there are siblings and even twins that have been brought up the same way, have had the same education and background but have completely different personalities despite sharing the same genes.
