One thing you notice when you run in NYC is that people don't look at each other. Not directly in the eyes. Sure, they check each other out as a potential predator or mate, but running time is not friendly time. We're on a mission, we've got to meet this goal, achieve this pace.
I found myself getting into the same practice. I'd warm up and circle my ankles, then take off on my route. Whenever I'd pass someone I would keep my eyes on where I was going, my mind on synchronizing my breath and steps (8 steps in, 8 steps out). Use the peripheral to make sure no cars or bikes are about to take me out, pay attention to the sound of my feet hitting the ground (soft like cat). Intensely internal. Then, I started passing fellow runners.
At first, I made tentative eye contact, not wanting to weird anyone out with too much. I've heard it said before that people only look into each other's eyes for longer than 3 seconds if they're going to mate or murder. If we met eyes, I attempted a smile. When you're focusing on all the other things (breath, steps, sounds, cars, bears chasing you through the urban wilderness) the smile really comes out as more of a grimace. Before you know it, you've passed the other person, only showing them that you're pretending to have as much fun as they are.
On my way back, I tried a different tactic. I shifted my focus to what was outside of me. The light, the trees, the path, the people. I made a point to say "Good morning!" to everyone that passed me, whether they had their Do Not Disturb sign on or not. A remarkable thing happened- people responded. They smiled back, or said "Hello". You see, this funny thing happens when you smile- the receiver's body mimics your smile to see if it's genuine. That means, whether it's a self-generated smile or not, you'll still create one in someone else. Smiling has all kind of benefits, science showing links to longer life, stress relief, and happier relationships. I found that with every person I greeted, I felt happier, like I was developing a deeper connection to my community and the world just by smiling and speaking.
Two fringe benefits? My pace back was faster than my pace out, and my voice was well warmed up by the time I made it home.
Next time you go out to practice your thing, do it with a smile. Let me know what benefits you discover.
