When you learn to ride a bike, it’s important to know the rules of the road. In my case it was my dad who taught me: ride on the right, wear a helmet, use hand signals, and so forth.

It’s all good advice.

But even when you know these rules, you still don’t know how to ride. Your brain, muscles, and balance system still can’t coordinate their actions to create a positive result.

In the world of preventive healthcare, it’s like being told to eat nine servings of vegetables, exercise every day, get adequate sleep, and the like.

It’s all good advice. Follow it.

But none of it trains your brain, digestive tract, kidneys, liver, and endocrine glands to coordinate their actions to create a positive health result.
