One dictator stands down , one holds strong in defiance

An ailing man, whom struck fear into the hearts of many for years with an iron fist steped down today. Despite his holding on way past his prime; he cited health as his number one reason for stepping down. He spoke with strong words saying , "it would be a betrayal to my conscience to accept a responsibility requiring more mobility and dedication than I am physically able to offer."
Was it Joe Paterno? No! It was Fidel Castro. You see, even a communist dictator knew when it was time to step down. You see even Castro had no problems letting go; in July 2006 when he was ill he ceded his powers to his #1 in command. Yet, Penn State doesn't even have that. Just a guy that calls the defense...and of course Joe would never relinquish power to anyone come hell or high water. Broken leg or not.
So now let me ask you this:: If a communist dictator knows when to hang it up; why doesn't Joe?
