What an odd story, having had both my adrenal glands removed beacuse of the tumours you get when you have VHL and the same can be said for my father (who had one the size of a grapefruit) and my brother had one too... this seems like nonsense. None of us were ever anywhere near violent. I've never even seen anything to suggest you look out for that as a symptom. In fact the extra adrenalin is more likely to make you depressed.
