Hep C, Hipsters And Tats — A recent article in the New England Journal of Medicine estimated that the number of people in the United States infected with the Hepatitis C virus is between 3.2 and 3.5 million.
The disease may go for years without symptoms but if left untreated
producse chronic liver disease, cirrhosis, and cancer. About 85 percent
of people infected with the virus develop such things. 
And what are the primary causes of the disease? Intravenous abuse of drugs and tattooing.
Just something to consider when making unforced lifestyle choices.
