I don't even wash my hands when I'm out camping/fishing. I'll be gutting a fish one minute and cooking supper the next. I just rinse my hands off in the lake/stream. Good enough.
I've never been one that goes nuts washing hands. I figure they get washed pretty good when I shower so I don't really wash them otherwise. Unless I'm preparing food for someone else, or have handled raw meat. Then I would wash after doing that.
I'm thinking this is part of the reason why I have such a good immune system. My parents never went all farking crazy and didn't make me wash my hands every other minute like I see some parents get all crazy about. A little dirt don't hurt nobody. And I hardly ever get sick. It's been like probably a good 6 years or so since I was down longer than a day with something.
