You should not pee or wash your hair within 50 feet of a natural body of water—stream or lake.
Regarding natural cures. I noticed green mold growing on an elderly orange. Then I remembered that most germs prefer and alkaline environment, but the orange was acid. Did some research and found the green mold was a penicillin. Rubbed a little on a pimple and it cleared right up. Good to remember if we ever have a major disaster. Grow penicillin on citrus fruit. Also, put a drop of iodine in a glass of water and let it sit for half an hour, then drink safely. Learned that from a guy in the Peace Corp. Did that with the drinking water in cafes on a trip through Central America. Never go the runs. Remember hearing about all the people desperate for water after Hurricane Andrew. If they had iodine, then no problem. Strain water through cloth, then treat with iodine and wait a half hour. Chlorine bleach works too. I just don’t know the amount.
Also, you should not pee in your hair, unless you’ve been stung in the head by a jellyfish and can hang upside down without a spotter.
