Thinking it was a trick of the light, I ignored it. But, it wasn't going away.
I put it out of my mind, I went off on the rest of my morning, the stretching, the run, the kata, etc.
Then, a shower, and shaving off the week or so of beard. It was still there. In fact, shaving had brought it to the fore. I leaned in close to get a good look at it in the mirror, scared as hell that it could actually be what it looked like. And yep. There it was, jutting off my chin at a jaunty angle, not seeming to care the pain that it was causing me.
My first grey hair.
Excuse me while I go and sob for my broken and lost youth.
