i think it's really important to eat well, sleep well and exercise well to keep the body healthy!
i don't want you to think that i disagree with you there in anyway.....in fact, i support all your views in your post - apart of course from your opinion on the efficacy of vaccines.
I know in my country (the UK) and in the US, people have big problems with inappropriate diet (in terms of eating s*@t as well as eating too much) so anything that will help that problem, I am all for.....
I suppose that I think vaccines and western medicine can help us as well.
