At some point in our adult lives we're all reduced back the childishness of our past. I've noticed this most when we're surrounded by a great tragedy such as the loss of a loved one. During a prolonged illness, we eventually come to the realization that we will die... that we are in fact dying, and that there is nothing we can do about it.
The one dying usually comes to accept this -- which is cruel to the ones losing mom, dad, cousin Edna, your best friend Mary Sue, your sister, brother, aunt, uncle, or significant other. How could you just ACCEPT this cancer, heart problem, pneumonia, deteriorating, debilitating disease? You should be fighting it! You should be stronger? I wouldn't let this incurable, unbearable, excruciating illness beat me! You're just surrendering, you're giving up, you're resigning yourself to die! HOW COULD YOU DO THIS TO ME! At some point the loss is no longer theirs... it is yours. This is why they say that funerals are for the living, not the dead... they've let go, even if we can't.
I'm okay with being ill, and I know my G-d will take care of me even if my body can no longer sustain me... but it's hard for my friends and family to see me this way. I don't think it's my time yet, I've much more to do, and I'm too damned interesting for Him to kill me off this soon... but it doesn't stop me from considering the harsh truth of our mortality. We're all ticking clocks with a draining battery... and we're all running out of time.
