Growing up dad never used hearing protection and as a result I did not either, and still do not as much as I should. We can always strive to do better and improve though, I typically bring my muffs if I know I am going to be just flat out running the saw all day, or if its my old homelite with literally just a deflector then they get worn.
We are lucky I supposed as dad is 64 and has near perfect hearing, and I was told at the annual hearing check that I had the best hearing out of everyone at the plant I work at out of about 600 people. This did actually make me stop and think "hey, I should probably do more to make sure my hearing continues to be this good" so if you are reading this, don't be like me, wear your hearing protection!!!!
