First off EEEEEWWWWW! 1,500 people were asked some bizarre questions recently by Daily Mail. Once of those questions was "Do you ever smell your dirty underwear to see if you can wear it again?"
38% said yes. And 12% said they've turned their dirty underwear inside out and worn it again. WHO ARE YOU!!?? I mean really? Do also dump the poop out of your kids diaper and put it back on? Do you re-use condoms?? You're groin gravy is there whether you know it or not.
To each their own but HELL NO not in my lifetime. I don't mind doing laundry.
