That one is easy to answer. Indonesia is a really hot place. Little kids like to be out in the sunshine.
I suppose the same goes for Hawaii. Does anyone know if he played outside or hid in his room as a kid? There’s a couple pictures of him outside smiling at the camera in Hawaii. The only other thing I’ve seen is some Indonesian kids gave him some icky chocolate but that doesn’t shed any light on playing outside or not. As a teen he played basketball but that could be an inside or an outside sport. Did he play another other sport or was basketball simply his high school PE credit?
