First time I ever read a book mentioning #suddendeafness, a handicap that hit me years ago.
That's a random affliction that will make you deaf or partially deaf in a course of a few hours. Most of the time (like me) you won't have ever heard of it and won't go straight at the hospital (as you ought to) - part of the disaster can be saved in some cases. Or else, like me, you'll just have to have to just deal with the aftermath : mono-sound with a lot of noise (tinnitus is our phantom pain).
