Fitter, happier, more productive?

If we’re going to really address wellbeing in its proper sense(s), do we shrug and decide it’s really up to the individual? Open the brochure drawer and leave it up to them whether they read it or not? Or do we open our ears, eyes and mouths and see wellbeing as a mutual responsibility? As something that we can not only all contribute to, but all gain from in return?
