Quest question, @LifeoftheSearchParty!
I'm definitely affected, which is probably why I'm drawn to the search for justice in so many brutal and mysterious cases. Intellectually, studying the manner, methods and possible motivations of a suspect is fascinating and educational.
I'm a ruminator by nature, always looking for answers to questions and solutions to problems. Personal assets and liabilities can often be one and the same, so I focus on crime as a healthier outlet to my tendency to dive into rabbit holes of information.
But there are nightmares, etc. Sometimes my curiosity gets too deep, too morbid, and I have to take a break for my own mental well-being.
