Vivisection is one of the few words that can adequately describe a wide variety of altogether unpleasant experiences; in a metaphorical use it expresses both extreme
pain and complete
vulnerable revelation.
Vivisection is the link between the cruelties of animal experimentation and the cruelties of betrayals by those we trusted. It's lying next to the person you love and being unable to touch them because some obtuse code of ethics prohibits it; you're ripped apart, leaving bare emotions exposed like too many ghastly rabbit eyes.
Being dissected alive, metaphorically for emotional experimentation or literally for bioloical experimentation, is just about as fun as it sounds and should not be pursued as a leisure activity. In the interests of empathy, vivisecting others should also be considered carefully before starting.
