Maybe.

I know I'm going to die. I've been with people when they died. And I'm seeing a parent living with the challenges of very old age. I know I'm going to die and I try to meditate on that and, as far as I can tell, I truly know it. And I see the value of that knowledge.

But in a way it also changes nothing. I'm still alive. I'm still going to die. Nothing fundamental has fundamentally changed.
