Do you think...

I think it's normal. If you aren't getting that dirty then it is EXTREMELY wasteful to change under garments twice a day. It isn't necessary and who has time for that? I say it's up to the discretion of the person. I am very popular at my college and only was my hair on Sundays and Wednesdays. I'm not poor I just don't need to. I always get compliments on how beautiful my hair is.

Well what are you trying to prove? That you like to get as close to stinking as possible? Hey chum - you're so close to it that you are it. That is how being smelly & dirty works.

soap is cheap so that's no excuse. you know, after awhile, the house will probably start smelling. if you don't change your undies regularly, how often do you change the sheets or clean the house?

it is true that depression can cause this. maybe it's a way of life for some people.

I forgot to mention that sometimes people who are going through depression can lose their will to maintain themselves.

It's gross. A normal person should change their underwear everyday. I change mine twice daily, but that's only because I like being super hygienic and love the feeling of fresh clothes/undergarments.
I don't care how poor a person is...hand wash them in the sink!

I think that doing both only 3 times a week is a little unhygienic.

I think the majority of people change their underwear EVERYDAY and they usually shower daily too.

I don't know why, but a lot of lower-income people don't bathe that often and I don't think they have enough extra change to regularly do their laundry.

Maybe cleanliness and personal grooming is moderated by a person's wealth.

Here's what I think... A normal human being should change their underwear at least every other day so that's about 3-4 days a week.
A normal human being should take a shower at least 5 out of 7 days a week.
