You are right, we will never know the exact mechanism. I think "Unsettled Matters: the Life and Death of Bruce Lee" by Tom Bleecker did a good job of covering what happened to Bruce Lee, the circumstances and medications the surrounded his death. On the Dim Mak topic, I agree that nothing of the sort was involved. People often focus on the delayed reaction in Dian Xue, but those who train and practice Dian Xue focus on instant results. Otherwise it wouldn't be very good as a method of incapacitating an attacker or enemy. A delayed reaction is a just a consequence of damage being done that wasn't or couldn't be treated.
