On a related note, I like this comment:  There is some correlation as a hygiene issue. My first wife had some mental health issues. One of the ways these issues manifested is in cessation of self care. I could look at the length of the hair in her armpits and estimate with reasonable accuracy, the last time she showered. This is not OP's circumstance at all. I understand that. However, my experience does explain why I'm relieved that my current wife naturally has almost no body hair. (She also doesn't skip showers either.)
