That brings up an interesting point. It is well known that organ recipients pick up traits of the organ donor. For example a sudden interest in sports that the donor had or a taste for a certain food, etc. So what would happen if the heart of the nicest person in the world was transplanted in to a serial killer?
Yes isn't that amazing!? They've even made movies about this phenomenon! Seems cells HAVE MEMORY! Perhaps this is why some things carry on through family lines? Cells remember from one generation to the next .... for good AND bad. Wow, boggles the mind!!
