There is alot of speculation at the moment as to whether an organ transplant can result in something of a 'soul/personality' transplant.
This has been brought into the public arena this week after a very tragic case of a 69 year old man from Georgia, USA. He received the heart of a man who had committed suicide by shooting himself. After recovering he sought out the widow of the man and described how he instantly fell passionately in love with her on sight and drawn to her. They ended up marrying and Sonny appeared happy and settled. But then tragically with no sign of depression leading up to it, he also took his own life with a gun! You can read more on this amazing story and research into this subject here
There is also another personal experience story on the same site here from a woman who received the heart of an 18 year old boy and then developed his tastes, which were totally contrary to hers before the transplant. I also took the time to read through readers comments and there were a few more similar cases in there.
This whole issue is actually the subject of scientific research here and in China, although many Dr's dismiss it, it seems more and more are coming out and saying it's possible. Scientists and medical experts freely admit the last mystery of the human body they have not unlocked yet is the mind and conscious thought.
Anyway I found both these articles very thought provoking and intriguing. I am a firm believer in the human soul and spirit going on after death, so the thought that they are imprinted on our bodies organs in not entirely unbelievable to me.
Just a totally fascinating concept and I guess it may have implications for transplants in the future, if it's ever proved or strong evidence is found to support this theory.
