The cost of a piece of metal in your eye.

If you are wearing eye protection you probably will need ear protection also. This is 1 of the most overlooked forms of protection ignored. The difference is you won't see the damage as quickly like eye protection. Years down the road when it's too late and irreversable.

very true... I already did damage to my ears (for me it was years in rock band, mixed with constantly listening to music with headphones cranked up... a lot of these iPhone using kids are in for a world of hurt when they get older) ... Now I wear ear plugs and such whenever doing anything where the noise level will be very high..
