These stardust-elements are all heavier than iron, and with the exception of iodine and selenium, none of them play any role in human physiology.
But you are right that the 4 elements of the Bethe-Weizsaecker cycle (C,N,O and H) make up approximately 96% of the mass of the human body.

I don’t bash Iran politics. What I criticize is the fact that many Iranians (runs in our family) avoid talking about the mistakes and real issues. We just get ride of the questions and telling, let’s not talk about them.

cheers,
interesting post, though:)
