Still, this season I haven't felt depressed by the extended darkness. In fact I feel upbeat about most everything. I'd not change a thing in my life even if given the chance. I'm pleased with relationships, finances, and the minutia of everyday existence.
Being happy is surely impacted by outside influences but it's probably more affected by brain chemistry. Clearly, there's an interaction between the environment and what's occurring in the old grey matter. Perhaps if the details of one's world are lined up right, then suitable endorphins are released.
