Interesting technique, yours, but what do you do if you get a cut on your ass?
If you can heal yourself, I suppose that’s rather impressive, but mortals probably have to ask a friend for help — which reminds me of a joke about a rattlesnake bite on the pecker...
Most cuts that occurred while fishing were on my hands, and I believe it’s supposed to be your own urine - so pee on a cloth and dab your rear end, I guess. Sadly, my applicator doesn’t reach quite that far, either.
