People can be ill, make a post, and suddenly pass away from organ failure, heart attack, whatever causes their body to expire. Not everyone is so ill before they pass that they cannot make a post. Many people have stories about speaking clearly with loved ones before the person passes.
Andreas' wife alludes to the fact that he was ill in her most recent posting on his Ener-Chi site. I think she wants us to buy into all kinds of theories which is happening because she won't state the simple fact of what happened to Andreas - either because it's not good for book sales/and/or because it could impact his legacy.
I believe it's WRONG not to tell because it calls all of the protocols into question. How can we make informed choices regarding his advice if we don't know whether or not his own advice caused or hastened his passing????
