To quote Prince, "I went to the doctor and guess what he told me?"

Guess what he told me!

He said, "Boy you gotta have fun with but no matter what you do you, don't be a fool! Make sure you don't mix for long periods of time without rest. You have perfect hearing and any random ringing in your ears is stress-related because you're overworked, drink too much coffee and don't get enough sleep..."

So that's good news. 

I told my wife I had perfect hearing and now I had documented evidence to prove it!

She rolled her eyes, shrugged and said, "well you still have selective hearing..."

I've been mixing a lot lately and I often play 3-hour gigs with the band so my ears get tired a lot faster because of that. A friend recommended that I should get my hearing checked to make sure everything was in order and I'm happy to report that my ears have a clean bill of health.

As for the rest of my organs, the jury's still out...

When you mix for long periods of time your high-mid sensitivity gets dulled so you end up boosting more frequencies in the 1 - 5 kHz to compensate.

And when you listen to your mix the day after, with your ears rested, you realize just how much harshness and excessive presence you've added in the high mids.

Like I I told my doctor this morning, "I need to know if I have any hearing loss in specific frequency ranges because I literally wrote the book on EQ and I need to make sure I'm hearing things the way other people hear them too."

So if you work with loud music a lot it might be worth it to get checked as well. Even if it's only for your peace of mind. You want to make sure the music you're hearing sounds the same to everyone around you as well. 

As far as mix translation techniques go, that's an impossibly advanced one. And since you can't check your mixes on other people's ears, you need to make sure yours work as well as they can.
