well, i havent worked my way into an older community group, but having teenagers keeps me in young ears to tickle. i tell them things about diet and toxins, junk food and raw, dentists and doctors and fast food. you name it. the kids call me Organic Steve. my yard water is famous. one of my kids took some to school because kids wanted to try it. they said it tasted like dirt. how is that for pure water compared to tap, or worse, pop?
i believe the thing to do is cultivate ONE relationship. be a mentor or big bro/sis. adopt a grandparent in a nursing home. they will spread the word for you and bring those that are willing to you. just like changing yourself changes the world, changing one other person changes the world twice as much!
