I read somewhere that he had surgery for a severe back problem and growths removed after a colonoscopy.
Considering that I don't drink or smoke, and I exercise regularly, it was quite a surprise, but they said it can be hereditary. After that doctor visit, I was put on medicine, and it's now normal, and has been for years.
So, I don't know if Perry had a history of it, or just hadn't had it checked, but high blood pressure can kill you very fast, and without any other symptoms.
