Some interesting facts about copper:
Copper has very powerful anti-microbial properties. For example,
a stainless steel sink will contain germs for two weeks while a copper
sink will be germ-free in two hours. This was confirmed by a recent EPA
study and is why most hospital door knobs, handrails, etc.,
are made of copper or plated with brass (a copper alloy).
Copper often is referred to by economists as "The Ph.D
Economist." It's used in everything from wiring to pipes and any
fluctuation in its demand is a good indicator of the health of the
economy.
