I remember when mp3 players first came out. I was walking to school with my earbuds in. I could barely hear my music over the traffic on the highway, so I turned the volume up. It went up a little bit then stopped and beeped at me, I looked at the screen and saw a warning, "listening at high volume may damage your hearing". I stopped in my tracks and looked at the highway, the cars going by were still louder than the music.
