What is your listening level?

Depends on the music, my mood, and A LOT on the time of day. I find I listen much lower early in the morning (6 am-ish) than I do later in the day.
I had friends over a few weeks ago and we were listening kinda loud for a couple of hours, and I turned it to where I listen early mornings (I have a stepped volume) and I was laughed at. It sounded way way low to me too and I thought something was wrong with my system.
It's kind of like how your eyes get accustomed to light.

But normally - 80db or so

I find it amazing that many of you actually measure the db listening level. I guess I am missing something, since all of my life, I just turn up the volume to the level I enjoy. It may vary for different music, different days or even time of the day. May I ask, why some of you have the need to measure your listening level?"

I have a db meter for other reasons (hi fi related, of course), so a few times I just popped it up and measured out of curiosity. I assume everyone just turns it up to the level they enjoy same as you do.
