Where did these lines come from?

It seems like everyone around me is in a very reflective mood. I guess I'm fitting into that right now too. I've seen a lot, been a lot of places, and met so many wonderful people. Some of whom have moved on, either in life or in new life. It seems as if the time I've had has been incredibly short, and yet, looking back, it's impossible for it to have been even remotely brief. I'm 42. I've been in ministry for almost 20 years and am looking at my life right now. Is this what I want to be for the rest of my life?
Considering that I have no idea how long my life will last (if you've ever seen alt 40, you'd probably wager with me that I've got a 50/50 chance of making it home tonight.) I have no idea what I want to be for the rest of it.
I don't have a bucket list, don't want to. I think it's a waste of time, because so many wonderful things come my way that to wish for big things is silly. But I can tell you that my time in parish ministry will be ending soon. Not today, not tomorrow, but in a while. I have no idea where God wants me to go next, but I know that it's different. I'm ok with that. now. I'm still struggling with the unknown, but that's ok too. I may never own that production company I've always dreamed of, I may never work for a great newspaper, I don't think I'd want that anyway, I'm in such a different place than I've been in the past.
I have such good freinds and such wonderful expereinces to look back on, I can only anticipate with joy where I'll go next. But can someone please tell me, where did these lines on my face come from?
