I can absolutely understand how something like that can dramatically impact one's life! I have had more or less constant tinnitus ever since, ranging from 'don't even notice it' to 'microphone feedback in my head,' but unless it's the latter, it's rarely an issue. I've also had relatively common, but varying degrees of vertigo. Both are typically related to stress and/or fatigue, so, you can imagine that this job, plus *gestures around* all of this makes that more or less daily. Funny what one can get accustomed to, innit?
