I have a wet fuse and a thumb switch detonator. Impossible to anger unless the subject or instance is truly important and/or getting angry will help. I decide when to get angry or stay calm. Getting mad about stupid stuff when it won't help anything is immature and a terrible waste of time and energy. Don't ever sweat the small stuff. There's plenty of big stuff to occupy your time.
Of course, too much booze skews the curve!
