There is some discussion that people with transplanted organs often take on the personality, likes and dislikes of the donating person. There are theories about this, one being that on a cellular level all your information is stored in every cell. A cell in your toe knows all the things you did as a child and all the things your arm has done today. Others take it a step further and say that our DNA carries memories and that what your grandfather did in his Navy days in WWII may not have stayed there, but carried on through his DNA into you. Today, you break into a navy ditty when you're nervous and have no idea why. You also like mayonnaise on your burgers and malt vinegar on your fries just like Great Uncle Bob did.
Taking this even a step further, what if we are not only tied by DNA and cellular memory, but also spiritually so that when a lineage dies off, the descendants have a constant playground of spirits around them in everything they do. A sort of soul DNA. You didn't choose that house on Elm Street because it cost less than the one on Oak Avenue. Your sister wanted you to live there and she chimed in with Great-Grandpa Milkins and your Aunt Betsy and the collective swayed your choices. Your blood is their blood, your DNA their DNA and their spirits your spirits...
So, what do you think?
