Exercise, from a public health perspective, is an unmitigated failure. The world's longest-lived people live in environments that nudge them into more movement. They don't use power tools, they do their own yard work, they grow a garden.

Public health and safety are my highest priorities.

People who are making it to 100 live in environments where they are regularly nudged into physical activity.

We are not for disarming people. When you have an epidemic it's a public health issue, a safety issue.

You can't have public health without working with the public sector. You can't have public education without working with the public sector in education.

Imagine a world where people were 10% happier and less reactive. Marriage, parenting, road rage, politics - all would be improved upon. Public health revolutions can happen rapidly. Most Americans didn't brush their teeth until after world war 2 after soldiers were demanded to maintain oral hygiene. Exercise didn't get popular until science proved its benefits. Mindfulness, I had come to believe, could, in fact, change the world.
