I'm not sure if you are joking here; do you agree that even gamma ray photons may happen to miss your body due to the quantum randomness in their emission and absorption events? > So there is a branching event for you: if you survive a nuclear > blast, how sure could you be that you really survived? Which brings up another possibility, which is that your body could spontaneously re-assemble from atoms in the environment even if it were temporarily destroyed. In that case you might have genuine uncertainty as to whether you really survived, depending on your views of personal identity and survival. Hal
