JM, as far as I know, he died of cereberal malaria, on the death march. My mother told me, that while her and dad were watching news reel footage, that dad was firmly convinced he had seen his brother in the films. Who knows for sure.
Temu, I was in Davao, Mindanao a few months ago. I liked New Bataan, in Compastela Valley, northeast of Davao City, but it floods too much. I will be moving to Davao City soon. It is not dangerous, like many try to say. It is one of the safest places in the Philippines. Now, in western Mindanao, it is not safe, but the east is good. I have been there many times. You can google earth Davao City and see it, right on the beach. I can't wait.
