nickelbabe you are obviously some kind of medical marvel, quite possibly indestructable, I would suggest you take yourself off for testing at the earlest possible opportunity.
What other expanation can there possibly be for you not dropping dead from washing with your pants?
Ffs.
According to the scary 'your pants are full of shit' link, most of it stays in the machine and contaminates all of your other washing anyway, unless you wash with bleach or at temperatures higher than the sun, lets hope none of the germs fearers wash their tea towels in the machine eh? Hate to think of you all smearing poo over your freshly washed plates.
I do everything I shouldn't apparently, I strip wash, I sometimes miss a day and don't wash at all, I certainly don't wear clean clothes everyday, sometimes when it is frigging cold and I am camping I don't even wear clean knickers everyday.
I haven't ever washed with my pants, but actually I think it is quite a good idea and I may take it up.
