Usage of noble metals

Topic: Usage of metals in the form of ornaments.

Myth: Its just a fashion in this part of the world which is in practice from ages.

Reason: In the early days as we say when human started dwelling on the earth, there was no law and order neither any humanity etc.. Only because of 'The Great Manu' our culture started developing. His laws are very popularly know as 'Manusmriti'. Only after his laws were postulated, the concept of marriage is there. In those days they used 'Tali' as a recognition that the women is married. Tali was mere a thread with turmeric paste and dried and a turmeric root tied to the thread. As my guess says there was something else which was used for the recognition of a married women before the usage of turmeric (This is merely a guess and no proof or logical thinking). Gradually some science development was in progress and only after some significant scientific research the turmeric root and turmeric paste is used for this purpose. As we all know turmeric has a very high medicinal value. The then scientists came to a conclusion, if its there on women's neck it will help in building a good health. Now you can ask me why they choose neck and not any other part of the body. Neck is the first part where we get sweat more and more as we start sweating. That means there are lot of pores here. Don't you think this would be a good place to keep the medicine which can gradually diffuse into the body? The same conclusion was drawn by our great grand fathers and hence usage of turmeric.
Now coming to the usage of metals on body. As I said science is not static it always progresses. Metals were discovered, slowly the usage of metals in the development of our health was also studied. Now turmeric is replaced with the gold. This started looking fancy and hence development of lot of ornaments and their usage. Now a days people take gold sol injections and you know the reason why they do. Not only gold, all the noble metals do serve the purpose of building good health. As a further development people started recognising the importance of the gems like ruby, diamond, topaz, etc.. and hence embedded them into these ornaments which look more fancy than metal alone.
One observation, I want to bring to your notice. When eye starts flickering and you report to your fellow friend or someone the immediate question they ask is which eye. For men its right eye and for women its left eye, if it start flickering then they say your luck will be good in the near future. But science says flickering is due to problem in blood circulation in that zone. When this happens married ladies use their 'Tali' touch whichever eye is flickering and after sometime the flickering stops. This is what made me think the importance of metals on our body.

Do correct me with comments if I am analysing in wrong direction.
