How Often Do You Change the Sheets on Your Bed? [POLL]

I was just reading a statistic that said that the average man changes his bed sheets every 45 days. That sounds like an eternity but then again that is only a month and a half. I would actually have thought it would be even longer. I am guessing every three months at the max. I also saw where the average guy sweats out 26 gallons of sweat into their sheets every year. Sounds like we need to start changing the bedding more often. That is rather gross.

Let's be honest here, how often do you change your bedding? Is it only when you spill something? Do you change them weekly? Monthly? When your parents are coming?
