The ultimate.

Death.

An unknown mystery that confirms the end of life.
*The most feared*
*The undefeatable*
*The unpredictable*

For homo sapiens, the fear of death, and the need to outwit it begins on the day of conception. A foetus, as undeveloped as it is, knows the smell of death.
The first thing an infant does after exiting the womb is scream for dear life.
But why all the fear?
If death is as natural as birth, if every beginning has to have an ending, why all the tiring fuss to avoid it?
