Sign language interpreters at metal concerts.
Actually, I am in pretty good shape for a couple of reasons. One, I have not been to the gym lately, so I have not been listening to metal at max volume in earbuds much this year. Second, I don’t tend to go to actual metal concerts because in my youth, metal heads tended to give me the business, so I avoid them in large groups.
But still.
