Shaving with cold water really isn't fun. Or trying to get rid of sweat and grime without soap. There's reason in this madness, though. Take ten guys all having a bath in a stream and there'll be soap bubbles floating downstream for hours for any enemy to follow back to find us. Not to mention that the fish don't like it much, either.

Added to that, shampoo and soap are scented. Of course. Why would you buy it if it didn't smell nice? But it's a rather obvious way to sniff out where the enemy is hiding. Some plants, on the other hand, make great natural soaps. They neutralise the scent of sweat and repel insects. And since the mosquitoes had a banquet last night… that's very welcome.

Problem is, none of the plants are ones I would have come across when cooking. I have only a very small, crumpled picture to use as a guide. And I'm standing in the middle of a wood that's - obviously - full of plants. So chances are the mosquitoes will emerge victorious.
