Sometimes I yell.

I have various ways of releasing pent-up emotion and stress.  Lately I've been yelling.

Not at people, or pets, other drivers, or really anything in particular.  It's not really even a yell per-say.  More of a guttural noise.  An expulsion of air from the diaphragm releasing a primal bellow.  

Some people like to cry to release pent-up emotion, especially when it is frustration.  I find exercise or excessive house cleaning is good for frustration.  (By the state of my home anyone could guess that I haven't been using the latter for releasing frustration).  I know that crying does release some good chemicals  into the brain, you can feel it when it happens.  A release and a slight cooling sensation.  I find the yelling (or grunting, as it may be more appropriately described) to have similar effect and much easier to call forth.  

Tonight I topped off a healthy bout of yelling, with a long session of hand watering in the garden.  Not really necessary due to the soaker hoses we've installed, but pleasant and appropriately cathartic none the less.
