Hey, You can get everything else on one, so why not a tampon? Okay,  just kidding, but this article from The Art of Manliness has a lot of very practical uses for tampons in an emergency. I mean, besides the original one. When TSHTF happens (and it will someday), a simple tampon could save your life in a survival situation.

My personal favorite is blowdart fletching, but all of the others are good too

Be sure and read the whole article. It could save your life!
