back in 1950 I was on the CVA Hancock, then the Shangrila then the Essex. I have a db floor of about 40 maybe more so I am not hearing real well anymore.
I also now have 60 % capacity left in my lungs and this is no doubt from breathing the asbestos in my bunk every night. There is a big class action going on about this, but collecting anything from the Gov will take a lot longer then I will be around

I've had it lightly for about ten years and I'm 27. I only notice it in the relative quiet. Does it get worse?

Excerpt from:

Tinnitus can worsen in some people if they drink alcohol, smoke cigarettes, drink caffeinated beverages or eat certain foods. For reasons not yet entirely clear to researchers, stress and fatigue seems to worsen tinnitus.

And...Certain drugs -- most notably aspirin, several types of antibiotics and quinine medications -- can contribute to the condition as well. In fact, tinnitus is cited as a potential side effect for about 200 prescription and nonprescription drugs.
