You only get one set of ears.
Protect them.
As a person with inner-ear damage due to exposure to high volume levels, it breaks my heart to see people sawing, drilling, or grinding away with no protection. You wear goggles to protect your eyes (I hope). Why would you not want to protect your ears? Next time a loved one says something that warms your cockles, think about what life would be like if you couldn't hear them.
