Unfit, fit, very fit, young, old, what the hell - anyone can croak it anytime, even pro soccer players! I believe if you croak it in China, your remains, or ashes, will need to be repatriated. I take it if you're a Westerner with a Chinese spouse and you croak it in China, the same will apply unless you have acquired Chinese nationality, damned hard to get it, in any case!
