Just a thought: some people seem reluctant to drink rain water because of all the airborne pollutants it passes through or collects as it falls.
If you're okay with breathing that stuff, what's wrong with drinking it???
The normal respiratory rate is 12-20 breaths per minute. That's 720-1200 per hour, or 17,280-28,800 per day. Every day.
I wonder if a person ingests more "debris" from breathing air or drinking rainwater?
