IB - the change in body smell: I think it is partly hormonal, but mainly I think it could be due to stress [which could bring about the hormonal changes too]

I have come to see a pattern in those who have MLC and they seem to be rather rigid people who do not deal well with changes and setbacks. In addition to childhood damage, I have noticed that many come from military backgrounds/families, or families with lots of rules. Change or setbacks stress them out to the point of parts of them 'shutting down'. Neurologically I suspect most of them move to their left brain hemisphere. Without good right hemisphere/left hemisphere communication, people operating mainly from their left brain hemisphere exhibit schizoid personality traits, a total absence of empathy, and an apparent personality change.

They are literally stressed out of their right mind. That could very well account for the change in body odour that so many of us have noticed.
