Truthfully, when I saw the speech I thought maybe he was stoned on pot. That didn't bother me and it was speculation so I kept it to myself. When he died and they mentioned heart disease I snapped to it. Puffy face, red eyes, something about his speech was off and he seemed generally tired.
As young as he was serious health problems never occurred to me but it fit in retrospect. Terribly sad and such a loss for all who loved him.
