Well, what an interesting thread.
For the ancient history buffs, in Vietnam most of us wore no underwear. The heat and humidity made undies prime locations for crotch rot. I don't know if that's a problem in A-stan or Iraq. In those days medical science had no long term cures for the various fungal afflictions we had. Mine kept recurring for many years, until a true anti-fungal was developed.
There. Now, aren't you sorry I dropped in?
