An old guy asked me one day when I stopped for a cup of Joe how I could hear anything with those things in my ears. I told him, "That's the whole idea." When I'm not in the mood for music I put in earplugs when I ride to cut out the noise from the wind and cars. Do whatever you're comfortable doing, just don't try telling someone else how to live their lives! Darwinism is great. Embrace it and move on!
