I'm 43.  For the longest time, i could easily hear all that stuff.  Some point in the past 5 years, on one of the ADHD medications I'm on, not only did I lose that range of my hearing, but I also picked up tinnitus... so now I ALWAYS hear it.  And since it's essentially nerve damage, there's not much treatment I can get for it.  Luckilly, the meds i'm on now (Adderall) kinda distract me enough that I know it's there if i listen for it or am thinking about it, but generally, I'm able to just ignore it... which is good, since the previous meds did nothing of the sort, and it was unbelievably tiring to hear all the time.  <br><br>Thanks for more great content, Tom. Be well.
