Being a PIMO may cause loads of mental and physical problems to us due to the excess of anxiety and stress. Depression comes from that type of stuff! And I know what I'm talking about! 30 years of being under the Society rule led to my depression a year ago, and I only started to really feel great after I took my decision to leave!
I can only see a good side for keeping being a PIMO (because I think that lying from the platform and when going door to door is also corrosive): it's when elders can handle it and leak secret info that people wouldn't have access to otherwise. But they really have to be careful with their health because depression settles in really slowly and quietly!
