"Because if you're going to bed showered but leaving those bed sheets for a month, then that is going to accumulate bacteria, dirt and dust mites."

A MONTH?!

As a young single male, how many people have a second set of sheets? I'd guess the average young single male changes/washes the bedsheets once a year, assuming no spills or obvious needs-a-cleaning mess incidents.

I’ve always had very oily skin (great for keeping supple, wrinkle-free skin.) I’ve gone a few weeks without changing sheets and the oil stains them horribly, NOTHING gets them out. And no, I don’t like dark sheet to hide the stains.
