Exercise is optional. Movement is essential.
In less than two generations, physical activity has dropped drastically. Vehicles, machines, technology do our moving for us. It's a new world, where being sedentary is becoming normal. The modern human has no need to run, climb, jump, to forage or hunt food, to escape predators.
Movement is ancient. Movement is more than exercise. There is simple joy in movement. Be present. Enjoy the moment.
