&gt; Sudden cardiac death

Look man I don't believe that the vaccines cause heart attacks or clotting or whatever but if you expect me to believe "Healthy young men have always died of heart attacks" you're out of your gourd. 

There's got to be a better explanation than "Yeah fit young adult males just keel over from heart attacks and that has always happened."

I have treated young athletes with no cardiac history for sudden severe cardiac episodes before. From the paper cited above: "In the majority of U.S. studies, the most commonly identified cause for SCD in young athletes is HCM, a genetic condition characterized by left ventricular hypertrophy and cardiac myocyte disarray predisposing to ventricular arrhythmias (Table 2).22 The prevalence of HCM in the general population is up to 1 in 200 individuals, and in many the first presenting symptom may be SCD."
