When someone is in a car with speakers so loud you feel the ground vibrate, do you wonder if they've already deafened themselves to the point that it sounds normal?

I take minor satisfaction in knowing these guys will be even more hard of hearing than the elderly usually are, and at an earlier age. You're going to see a lot more middle aged people with hearing aids in a decade. One day I want to see hundreds of videos of them expressing regret for playing their music so obnoxiously loud. Of course, they won't consider the annoyance they've posed to others, but the consequences are even sweeter.
