Mad Mercury

Many of us are familiar with the character the Mad Hatter or with the phrase “Mad as a hatter”. Have you ever wondered how that came to be? Why they turned mad? In the 17th century hat makers would use felt treated with mercuric nitrate. This practice went on even in the 19th century. The symptoms included were: drooling, trembles, talking to one’s self and having bouts of severe paranoia. This is due to the mercury seeping into the central nervous system over time. Later this would come to be known as Mad Hatter Syndrome. Now let’s think. If introducing mercury over time into your body results into you turning into the mad hatter, then would you even go near it?

Can be even levitra vs cialis to be interesting to all who will come. But it seems to me that more interestingly staxyn vs levitra here about what you don’t know and it would be necessary. Because the more a variety the better for all.
