Having had too much unprotected exposure to guns, chains saws, and rock 'n roll in my earlier years, I recognize that the foolishness of youth has given me some tinituss - but only enough to realize that I need to wear hearing protection now whenever doing anything loud - like shooting.
I usually wear "in the ear" earbuds now all the the when shooting ... or chain sawing. Not much loud music for me anymore.
I'm also inclined to don eye protection while engaging in many more activities than I used to. This is because of my only ER experience, which was recent.
Your body has amazing ability to heal, but ears and eyes are not included.
