O. J. Simpson is Type A

I find an article of "Stripes Okinawa" (Stars and Stripes) on blood type and personality.

This article is written with a light touch, so you can enjoy it.
The compatibility between type A and type B is said to be bad.  In fact, the author of this article is Type A and his wife is Type B, it doesn't matter because the couple has been satisfied for 25 years (laugh).
FYI, according to the article, O. J. Simpson is Type A.
