What's the longest you've ever gone without bathing or taking a shower? Prepper Ideas

Just curious.

While watching The Walking Dead, that's the one thing we don't (thankfully) have to be bombarded with-the stench. Because you know in the Zombie Apocalypse (ZA) people won't be showering every day, or even every week. Let alone the frikken reeking Dead. Pretty sure a real-life ZA would be handled differently by today's SJW crowd! (what a comedy!)

When there is a massive power grid failure, and the water pumps go down without electricity, how will you wash?

In the "Wild West" is was said they took baths every Saturday, so they would be cleaned up for Sunday church. So we know by historical data that many went without bathing for a week, usually.

As for brushing your teeth, that must be done at least once daily, preferably after each meal.

Any military-types in here want to give us the skinny? After a mission do your skivies walk away on their own when you take them off? Or are they too brittle to move?

I've found that I can cold shave for an entire year with one razor head for my manual blade. No soap or foam. It hurt for a bit, but you get used to it. By keeping the blades clean they will stay in decent enough shape. Oh, it was also my Wife's 'Venus' razor that I grabbed before she pitched it. Those last and work great. No more buying recharge blade heads.

Just a thought. How 'bout you?
