 You know, my friend Michael Easter, who wrote a book called The Comfort Crisis, has created a thing called the 2% Club. And he sells these hats that just say 2%. And I'm like, what is this? And he says, 2% of the people in the United States, when given the choice between an escalator and a flight of stairs, will take the stairs. And those people invariably live better, live healthier, outperform, out-earn everybody else. So you're on to something. Right. I'll tell you, I do do the stairs regularly.
