Hypothyroidism has several causes. The first of which is a deficiency of iodine. Iodine is found in shellfish, shrimp, salt, and other foods. If a person does not get enough of these foods, they will not receive the proper amount of iodine that the thyroid needs to function at its best.
Introduction. Japanese samurai were warriors of the shogun rulers during feudal times. While their origins are unknown, what is known is that they were fearsome in combat and were fast on horseback. In the 8th century, Japan's government sent warriors to subdue barbarians in northern Honshu.amurai were expected to be fearless, loyal servants of the samurai lords, the daimyo, while leading a plain and simple life. These warriors made up a very small portion of the Japanese population, while the rest of the population were farmers, merchants, priests, monks and artisans.
Samurai women. Japan under samurai rule was male-dominated. Before this, there were a small number of female rulers and some women were allowed to inherit property. From the time of the civil wars fought in the Heian Period (794-1185), it was thought that a man should be at the head of the family to protect the house and land.
