Cellular memory - Wikipedia, the free encyclopedia That Wiki is pretty incomplete. I'm watching a programme on it now. People who had heart transplants have after their operations taken up the habits, hobbies etc of their dead donors. It's really strange and does raise the question of whether our consciousness does actually live on? What do you think? The official medical opinion is that its just the medication or due to stress after the transplant. But people have had such drastic changes eg dreams of their donors. One had a dream reliving the murder of her donor and correctly identified the killer and he was caught. Another woman started craving 'cheese doodles' and M&M's when she never liked them before. And she took up karate. Her donor loved cheese doodles and M&M's and was heavily into the martial arts. Any thoughts on this? Its quite interesting.
