MINIMUS:
Yeah, personal hygiene is very important and over the years I have encountered smelly people.
They come in a few categories:.. people from cultures where indoor plumbing was scarce and not in the habit of daily shower/bath - and they forget they are NOW in a place where there’s soap and water; people who are products of broken families/drug culture - and certain senior citizens way over 80 who perhaps grew up in depression era where there wasn’t easy access to a bath tub. Also, people need to put clean underwear on daily!
Whatever the case: hygiene needs to be taught all over again. We are going backwards in a lot of ways. I might also add that things like bedbugs are back - meanwhile these things were eradicated back when I was growing up. This is also an unfortunate by product of people immigrating in large numbers who are not assimilating!
As far as the smelly guy you mentioned: somebody like that I have no tolerance for and he deserves to be alone - unless he’s with a woman just as smelly as he is.
