Better deaf than dead.
I served for 10 years in the Field Artillery (M110a2 and M109a2/a3).... I had several occasions when I did not have earplugs/headset/CVC helmet on and got whacked with way more muzzle blast than a handgun would impart. I spent many hours in close proximity to large diesel engines in teeth rattling tracked vehichles and Very Large Trucks at Ludicrous Speed on various Autobahns ...... hearing damage is cumulative........
My hearing is not perfect, but my quality of life is better having done what I did then than if I had than if I submitted the whims of .... "persons"...... who would offer me violence like the Wisconsin State Fair deal...... if only "pour l'encouragement des autres".... "when Good Men do nothing, Evil is unopposed."
