Tinnitus is a persistent ringing (or other noise) that one hears when there is no actual noise to be heard. I've suffered from an irritating, but much less than debilitating, version of it for 10 years or so. Some people's tinnitus is so bad that they can't work, read, watch TV, or enjoy much of life.
Now some scientists say they may have an actual cure, one that involves “rebooting the brain”. Hmmm. Are they telling us that our brains are equipped with Microsoft software? I sure hope not, 'cause that's a mighty scary thought!
