I wonder what mathematics and science can do for the psychological well being of those with bipolar and other challenges in their brain functions on their emotional well-being whether nature or nurture. For me when I get the most stressed and my brain seems like it has taken in way too much envionmental stimuli I do a math problem and it helps my brain calm down and focus which produces a sense of control on my unpredictable environment which in turn contributes to a sense of a mental "runner's high" producing serotonin etc. helping overcome my negative overproduction of cortisol (stress hormone).
