I think I was about five or six, but I developed this fascination with burping, sneezing, hiccupping, etc., and came up with the idea that if you did several such things at the same time, you would instantly die. I was sure that my dad knew the answer, but I couldn't just ask him straight out. I would say, "What would happen if you cough, sneeze, fart, burp, and hiccup at the same time?" I would be dissappointed when his answer didn't involve death. So I would re-phrase the question, (e.g. sneeze, hiccup, burp, cough, and fart), to try to ascertain the correct order. I was sure some combination would be lethal.
