It was almost zero visibility and -23F wind chill. Your balaclava is caked in frosted breath and it hurts to breathe. You're going fast, faster than you should maybe (then again it's hard to tell when you can't see far). Your ski catches an edge on a hidden bump. And you flail. You're convinced you're going to eat it. For sure. You brace for the tumble, for the pain. And yet... a fortuitous gust of wind. Or something. You get your balance back. You whoop under your breath - you're not the kind of person who whoops out loud. For that short split second you feel... invincible. 
Hope you're finding joy, wherever you are.
