I've worn earplugs for at least 12 years. As for devils comment, in my experiance once you get used to them you find that they actually highten your awareness of whats going on as they block out the insignificant background noises. Therefore you concentrate on what's important.
However, the most important reason for earplugs is the protection they give to your hearing. Wearing a helmet and travelling at any sort of high speed gives your hearing about a 100 db. blasting. I know that someone will say,"I wear a ----- and it's very quiet", but a study in England has proved that long term exposure to the type of noise you get while wearing a helmet WILL dull your hearing. It's only a matter of time. Then you won't need earplugs 'cause you'll be deaf as a post.
I SAID YOU WON'T.......oh, never mind !
