I don't care about the time I run. I can try all I want, but I doubt I'll ever be able to run the way I used to. I'm ready to accept that. It's not one of your happier realities, but that's what happens when you get older. Just as I have my own role to play, so does time. And time does its job much more faithfully, much more accurately, than I ever do. Ever since time began (when was that, I wonder?), it's been moving ever forward without a moment's rest. And one of the privileges given to those who've avoided dying young is the blessed right to grow old. The honour of physical decline is waiting, and you have to get used to that reality.
