How does your personality affect superstition?

Borrowed from the Chinese, the Japanese have used their ancient calendar consisting of twelve animals and ten conditions. The twelve animals are called Juni-shi. The animals are Ne(mouse), Ushi (bull), Tora (tiger), Usagi (rabbit), Tatsu (dragon), Mi (snake), Uma (horse), Hitsuji (sheep), Saru (monkey), Tori (rooster), Inu (dog), and Inoshishi (ox). Just like in the Western zodiac, personality traits are assigned to these animals too. For example, someone born in the year of the Horse (Uma) would be inclined to be hardworking and conscientious.

Blood types also do matter in Japanese superstition. The Japanese believe that different blood types depict different personality traits. For example, a person of blood type B is deemed to have originality, but is fickle minded. Even though doctors and scientists nowadays say this is wrong, many Japanese people still believe in it.

Some general superstitions that the Japanese have include whistling at night. They believe that whistling at night will attract snakes. Also, they believe that if one cuts his nails at night, he will not be with his parents when they die.
