Could be. I am writing an article on his life and death. He posted on FB at 5am on Vitamin D and calcium and at 9:08am someone posted on Twitter he had died. So up until the very last moment he was working to save the world. So if he was able to work, he was not bedridden which makes the mystery even more intriguing. I am doing research to get some answers but the only answers lie in his following, his legacy and his life. I imagine some one will say one day what happened, but for now unless someone comes forward people will imagine the worst.
