Ah, yes!

Body fat. Enough said. I certainly have plenty of it, which is why I don't bother to take the "extra food" suggested as the whateverth essential.

Socks as gloves (if dirty, might be a bit smelly).

Plastic bags as glove overmitts.

TP (if I don't need it for its original purpose, which I usually do) plus hand sanitizer, a great fire starter (although I've never needed a fire yet, and if I do I'd use the firestarter I have in my emergency/first aid kit).

As Jim says, sometimes we get a little ridiculous on this multipurpose bit. On the other hand, it's nice to know we have some backup, however weird, in case the excrement hits the fan!
