I agree with Daryles approach.

Thinking back to my youth and the things I drank water out of without a thought of cleanliness...has to be part of the way my immunities were built up. The bigger danger in Texas summers was the water being too hot and might burn the mouth. Maybe the heat sanitized the "supply line/hose/pipe/trough/pond/lake/creek"??? Yuk!
