E.g. metal Therefore no matter how hard that you rub a metal tap no static charge will build up because the electrons that you are giving the tap just keep on moving up the tap and down the water line until they reach a ground. Insulators do not allow charges to flow through them.

Scientists continue to discover important links between vitamins and the risk of developing illnesses such as heart disease, cancer, osteoporosis, and high blood pressure. What is being uncovered is far subtler than the miracle cures of the 19thcentury deﬁciency diseases, but people cling to the belief that taking more vitamins will cure
