Not to die

Why do we try so hard not to die?

One moment, you are alive.
Next, you are dead.

What does this shift in the state really mean.
Everything that we are, we have been, and we would've been ceases in a single moment.
A simple malfunction inside our body could cause it.
If it is so important not to die, why are we not built more robust.
Or do we think it's important not to die because our life is so vulnerable?

At times, it is inevitable.
Many cases, it is predictable.
Some are said to be excusable.
We all wish the possibility of it to be forgettable.
But when it does happen, we want it to be memorable.

However you arrive at it, death separates you from the life you once belonged to.
You can never go back to it.
Many times it's abrupt and indeliberate.
But the change still is permanent.

Maybe we are all dead by default and being alive is a temporary change in our status for a limited length of time.
Maybe that's why we put so much meaning in "being alive" and "staying alive"...
