for those that might care, i RO my well water (screen-pre-RO-post filters) into 6 gallon containers, and then distill a gallon at a time. Each gallon of RO water takes ~5 hours total, including the time for the RO to process the water. My RO is very slow, but i am unwilling to pay for a jet pump for it, currently, to speed it up. It takes about 7-8 hours to fill 6 gallons, and it should be able to fill 6 gallons in 3 hours or so - it is a 50GPD filter system, so ~2GPH.

from my experience, only people who are serious about their mouth health and go to the dentist at least twice a year, seem to have healthy and good looking teeth.
What nonsense
What an offensive statement. Based on what? N=5 observation?
And the average european has much better tooth health than the average u.s. citizen, in my experience.
