Sure I have no clue about all ships, but of shooting, I do. And of mental health too, as well as hearing loss, accidentally being a doctor

So do yourself a favor and go trolling someone else. Bye. Don't bother answering, I won't see it.
Dr. VERY good. I went to high school with some that became Dr.'s.
One was mine after he did such.
But in the 70's, few, knew what is generally known now.
& I am a huge advocate of using all that is available to keep hearing loss from happening to begin with.
So, I applaud your getting this out and spreading the word.
Too few people do that.
And too many people get the knowledge too late.
It is something that should be taught in early grade school: loud noise & long term not so loud noise WILL
(not MAY) harm your hearing.
I just accept that mine has been harmed by my own activities (and a lack of knowledge).
When I can't understand people's voices, I'll research what steps can be taken to mitigate that.
By the way, I thought you where trolling, the way you worded things.
I was just stating facts about my experience's.
It's hard to interpret just the written words intent many times.
I am blunt & to the point, most times.
That puts many folks off.
With 14 trips through the Panama canal, a couple of Degree's, but mostly been all over Europe,
Asia & the tropics of the Indian Ocean & Western Pacific Islands (Home for 20 years),
I've never been called a troll. Interesting.
