Here follows more useless science. Dare I say it - another rationalisation to defend religion, altruism and 'positive' thinking. Such studies are performed despite the gaping contradiction of the study....its lack of relevance to the broader community. The study professes to look at Catholic nun's with the intent of determining the relationship between their brains and their 'positive thinking'.
The reality is that a nun is a parasite whom live off the guilt-induced efforts of others. They might be non-judgmental, so they are beyond judgement for most people - except me - but they are parasites regardless. They stand alone in that respect. We love to critique the parasitism of others like the unemployed, whom I would suggest mostly want a job, its just that they are validated or financed for doing nothing, so they just cannot motivate to do more than is required.
The guilt or ideological rationalisations which prompts you to support them is fuel for their happiness. They will live well on it. The 'unhappy' nuns are the one's who question their relationship to the world and realise that they are really the 'selfish' ones; but I don't like to call them selfish because they are really simply just 'anti-life', caught in a prison of personal ineptitude. i.e. Prisons of their poor early childhood decisions. Like doing the military.
The bigger target here are the researchers though who think science = correlation. Wrong! You need a theory of values. Your studies on nuns is not directly applicable to the broader population who actually work; moreover because they have a guilt which you seamlessly might avoid by 'virtue' of your utter righteousness. After all - who but me - would shoot down a nun 'metaphorically'...God's poor messengers.
