(Story time.) I went to a presentation one time at work about mental health. (It was part of the government's mental health awareness campaign[0].) In this presentation, the presenter mentioned bathing/lack of changing clothes as a marker for possible mental health issues.
As someone who grew up in a very poor area, where the water came from wells (which oft could dry-up) or the folk couldn't afford but to wash their clothes once a month in the local washateria (if that), I took issue with this idea.
From a privileged, lower-middle class or above perspective, sure, you could say that it's a possible indicator of mental health issues; however, if this were a normalised version of someone's life, having growing up so poor/destitute, would it really be a sign of mental health issues or would it just be a byproduct of their lower social-class life?
So, I guess I have to say that the answer to your question is, "yes": Your "norm" could be vastly different from someone else's.
