I think we are in a league of our own on that. However, I look at and know of many "normies" who really do appreciate the breath they have. For instance, my step-mom's daughter was murdered (my best friend) some years ago and due to her deep reliance on God and her faith, she has an appreciation for life that most can't fathom.
I think concerning "normies", that it really depends on their approach on life... their empathy for others... etc...
But as far as us addicts go, we have truly a different type of appreciation on things. That's just my thoughts on it anyway.
