We tend to treat health as the thing you get around to once the rest of life is sorted. The course flips that: optimal health and wellbeing is a resource that pays out three times over, to the person, to the nation and to the world. Choose a scale, raise the health level and watch which bars grow and which costs shrink.
Optimal health is a resource: it gives a person the energy to work and connect, saves a nation health system costs, and keeps disease from crossing borders.
