You can lead a horse to water, you can even put Iodine and borax in it but you cannnot make him drink. Horses being smarter than people probably WOULD drink!
I feel your frustration but take some comfort in knowing how many people here have learned from you and the other pioneers here and are healthier and happier because of it. This includes me and I pass on that same wisdom and experience every chance I get. A lot of people won't heed the advice but some will and those are the ones who need all of your and now my knowledge. Just keep sharing your pearls of wisdom and leading by example.
