Sometimes the Walk Doesn't End

I've been walking all my life, longer than I can remember, and it wasn't always my choice, but I keep walking, and sometimes the walk doesn't end.

How exactly does someone keep walking, against all reason and stamina and biological need, except to say, Sometimes the walk doesn't end?

I no longer separate the concept of walking from the idea of existing, because sometimes the walk doesn't end.

It's a fact of my existence, that sometimes the walk doesn't end.
