I am sorry to hear this Andy. MY personal opinion was it was just his time. Until there is a COD, I wouldnt wrap my head around it. Obviously, the climate affected him; whether he was having medical issues, caused by the climate, or just simply medical issues that were exacerbated by the climate, we simply dont know. Too many what ifs. Its horrible to lose a friend-my heart goes out to you. I sincerely hope that, in time, your pain eases.
