The researchers at the University of Michigan learned that old copper water pipes used in households lead to amassing of the metal in human body, thus creating various health problems early in life and becoming fatal as one crosses 50.
The study revealed that copper and iron may be vital when one is young, but with age the body cannot deal with such elements effectively. Therefore, people are advised to donate blood frequently to cut iron levels, and take additional zinc to bring down copper levels in the body.
