One thing a survivalist can learn from a woman, who's always prepared with a tampon in her bag, is that a tampon truly is an emergency tool.
The tampon, deriving from the French word "tampion," meaning plug or stopper, has been used since the 18th-century to absorb blood from bullet wounds. When you're in the wilderness, the multi-purpose tampon is a must-have in any survival kit. From first aid to water filtration, the tampon makes surviving possible. Period.
