Resentments. Have a few? Pull one up. In your mind relive the situation. Someone did someone do something that you find unacceptable? Completely unjustified? Do you ever find, in your head reliving the situation? In your head you imagine that you wish you had said just the right thing at that moment to put that person in their place. To save face? To take them down a peg? Do you ever find yourself ruminating over things like this? If you find yourself doing this, when you do, notice the volume of your tinnitus. And then don't do it anymore. It can be a real killer.
