So, do you guys think that who we are could exist at some cell level. That all of our cells know who we are and what we have experienced because our entire body shares the information at the cell level? Or is that just plain crazy? It certainly would explain this experience:

Cheryl Johnson, 37, says she has changed completely since receiving the organ in May. She believes that she must have picked up her new characteristics from the donor, a 59-year-old man who died from an aneurysm.
Now, not only has her personality changed, the single mother also claims that her tastes in literature have taken a dramatic turn. Whereas she only used to read low-brow novels, Dostoevsky has become her author of choice since the transplant.

Academics in America have developed a theory called cellular memory phenomenon to explain the personality changes that are allegedly experienced by some transplant recipients.
Examples include a Massachusetts woman with vertigo who became a climber; a Milwaukee lawyer who began eating Snickers, having always hated chocolate; and a seven-year-old girl who had nightmares about being killed after being given the heart of a murdered child.
However, the only case recognised by the scientific community is that of a 15-year-old Australian girl whose blood type changed following a liver transplant.

It would also give new meaning to this passage:

Ephesians 4:15 Rather, speaking the truth in love, we are to grow up in every way into him who is the head, into Christ, 16 from whom the whole body, joined and held together by every joint with which it is equipped, when each part is working properly, makes the body grow so that it builds itself up in love.

But I’m open to more scientific explanations, why do you think this happens?
