I had never heard those things about a virus in the heart....I probably have one drink a year and never used IV drugs. My cardiologist said it one of the main reasons was a lowered immune system, often caused by lots of stress in a person's life.
Mine came from a few years of helping my elderly parents until my father died one year, my mother the next year and my 34 yr old son the following year. I thought I handled everything well but had no idea what the stress was doing to my body.
I knew that Randy had recently had a DUI but didn't know he had alcohol problems.
But I don't know that anyone should assume that alcohol and drugs are what causes physical problems.
