Magnetized underwear. Wouldn't work for me. I tend to hold open/close the church doors with my hips when my hands are full. Although I might never lose my keys again. :p Then again, I really don't want to attract the punk rockers covered in metal studs either - that could get highly awkward. (Excuse me, could you not wear metallic nose studs?)
My friends, and friends of friends, had this to say:
"I wear some of those. Man is it a pain to get through airport security!"
"Imagines sitting down on a metal bench and not being able to get up."
"...walking by the fridge and getting sucked into it. You can't pull yourself away. What do you do? I guess eat everything out of the fridge until husband comes home to rescue you."
Isn't technology amazing? (Snerk)
