How often do you change your sheets?

This morning as I was stripping my bed to do a load of laundry I realized it had been a full two weeks since I'd last washed them-which had me wondering if there were adverse side effects to changing them at that rate. This also got me curious as to whether or not, relative to the rest of you out there, washing sheets every two weeks is considered slacking or standard.

According to examiner.com and ehow.com, the scientific consensus is it's best to wash sheets weekly to ward of dust mites. Icky as it is to think about, we're all shedding skin cells while in bed-which is apparently dust mites' favorite snack food. Laundering bedding once every week, in hot water, helps avoid allergy issues.

Washing sheets every week is a fair amount of work though, especially once you start counting multiple beds/family members, so it's no wonder a poll on AOL Health last year showed that only 40% of Americans are washing their bedding weekly, which makes me feel slightly better about my own every-other-week habit. What about you: how often do you change your sheets?
