“What’s so funny?” my son asks all so often when I come home from running, swimming or any other training. “Why are you smiling?”
Well, there are many things I could answer him, from neuro-hormones like Dopamin all the way to blood-circulation and the nicer number on the scales tonight or even the feeling of an empty mind, that has been filled with thoughts beforehand.
But I like to tell him stories.
“Running,” I like to give him as an answer,” is good for the Planet.”
