I like your approach. I always tell my kids that they shouldn't tattle but to make sure they are doing what they should be doing and not monitor others. It's up to each person to tackle their own health issue and support of family and friends is helpful.
I also feel the government is missing a key component of this issue. There are so many xenoestrogens in our environment that we are not trying to eliminate, they come from meat pumped up with estrogen, milk, birth control contaminants not filtered out of our water system, plastics, processed foods and more. Our whole society is over estrogened (men too, they live in the same place and eat what we do) that we can't control our sugar habit because it's hormone induced.
You have inspired me to start my family walks again. Thank you.
