Easy now mate, your life is not in danger, you don't have to bring forth that side of you for a simple discussion about opinions of understanding a subject which is unclear (the exact formulae, how much various parts weights is not known.)
I do it myself from time to time, but I am not proud of it. When all comes to all, discussions are about sharing opinions, and possibly, not necessarily, reaching a common understanding.
We don't have to put our ego into our beliefs. When we avoid it, we can have much more fruitful discussions. When we give the ego too much influence, we are basically in an altered physical state, which is not healthy, but can benefit if you truly need that extra energy when in physical danger. You basically shut down digestion to a certain degree and alike.
Stressing is kind of the same, an altered physical and mental state. No hocus pocus voodoo stuff here.
I am not trying to convince you, read it as I share an opinion which I genuinely believe in.
I am not perfect, that's why I am so interested in this. I am trying to help myself (it is a very good thing to remind myself of if I am slipping into bad mood of any sort.)
