Amazing at dying slowly 
Tinnitus Talk Support Forum
There's a lot of confusing parts of the human body. Mainly on this forum its the confusion of the body enjoying loud noises but not being able to repair damage caused by said noise.
At least the brain is still smart enough to figure out how to trigger the genes responsible for repairing hearing damage. Just not in the species itself.
@ThomasF what do you mean by that second comment? im bad at biology :3
@Safari1999 There are a few studies trying to target and activate the genes responsible for progenitor cells in the Cochlea to transform into functioning hair cells. The tests so far have been on mice but are nonetheless promising.
