I wash my hands after using a public restroom. Then I grab the door handle when leaving and feel like I’ve just wasted my time. Many people don’t wash their hands, so what’s the point? 

When coming up to a fight, I could pick up a head cold. Although no one would know my breathing is greatly compromised, I’d be at a huge disadvantage. While this possibility is always lurking, I just don’t allow space in my head for worrying about it. And so I deal with handshakes, countertops, door knobs and handling money without trying to drive myself crazy.
