Earplugs at concerts back in the day

Anybody else smart enough to save their ears back in the 60’s-the 80’s?I’d usually put a pair in, and pulled or pushed them to a depth that allowed me to hear (most) everything. My friends laughed. I didn’t care.
Thank God I did! I’m 67 now and still have perfect hearing. Way up in the highest registers as well (according to my daughter and some app she had me listen to).
