It always amazed me how many stupid ideas the WTS had about blood and how many jws still believe them.

Are idolatry and fornication damaging to the Christian personality? Disastrously so! So too is the taking in of blood, whether through blood foods or blood transfusions, for the Christian governing body has included this in the same category as the other evils. Moreover, recent medical research has indicated in a realistic way how blood transfusions may damage the individual’s personality. According to one authority: “The blood in any person is in reality the person himself. It contains all the peculiarities of the individual from whence it comes. This includes hereditary taints, disease susceptibilities, poisons due to personal living, eating and drinking habits.” Transfusing blood, then, may amount to transfusing tainted personality traits. How great the danger may become if the blood is taken from blood banks to which criminals and other derelicts of society have contributed! Wisely and in faithfulness the Creator of man guarded against this, and other harmful consequences, by his law forbidding blood.—Lev. 17:11-14.

A peculiar factor sometimes noted is a so-called ‘personality transplant.’ That is, the recipient in some cases has seemed to adopt certain personality factors of the person from whom the organ came. One young promiscuous woman who received a kidney from her older, conservative, well-behaved sister, at first seemed very upset. Then she began imitating her sister in much of her conduct. Another patient claimed to receive a changed outlook on life after his kidney transplant. Following a transplant, one mild-tempered man became aggressive like the donor. The problem may be largely or wholly mental. But it is of interest, at least, that the Bible links the kidneys closely with human emotions.—Compare Jeremiah 17:10 and Revelation 2:23.

♦ According to a report that appeared on United Press International of August 18, 1970, the daughter of Philip Blaiberg said that he had experienced a complete personality change after undergoing a heart-transplant operation. Blaiberg was one of the first to receive a transplanted heart. His daughter observed: “I don’t know if it was the drugs or just the transplant, but he was a different man.”
