I did a search on bathing, & didn't get much. Maybe it's not important to all the guys here, 'cause guys think sweating is cool.
We women think differently, so here's a little clue I picked up (from TMEN, I think). Granted, if you're short on drinking water, bathing is not an option. But sometimes you're somewhere where there's sufficient water, but not suitable for bathing.
Heat up a quart of water to a comfortable temperature, & add 1 tbsp. of baking soda. Wash all over with a washcloth.
That's it. No soap, no rinsing. And it really cuts that greasy sweat, & leaves you smelling fresh.
But you do have to wash out the birdbath when you're finished -- sorry, it's not perfect. <img src="images/graemlins/grin.gif" alt="" />
