Here is an illustration of NPA and ABO types. This is in the movie Dr. Zhivago, a story of the Russian Revolution. Russia has nearly equal numbers of ABO A, ABO B, and ABO O. Dr. Zhivago is a kind soft spoken doctor but self confident doctor who doesn’t survive the revolution. He falls in love with Lara, a victim of an older and worldly wise wealthy man who survives the revolution rather well. Pasha is a very idealistic angry young man who becomes a leader of the red army in the revolution. He doesn’t survive the war. Zhivago’s half brother is an official of the new Russia so survives it all, loves his brother and tries to help him.

Dr. Zhivago is an N and ABO A (low temperament)
Lara is an N and ABO A (low temperament)
Baryshnikov is an NPA+ and an ABO O (high temperament)
Zhivago’s brother is a PA and an A
