Image Factory: Death Clock? Panel?

Upon various Google searches about time and death I came across several websites with the concept of a death clock. These are websites which upon entering some details about yourself (age, BMI etc.) will predict when you will die.

From visiting these sites an mulling them over I thought of an idea for a panel in my triptych:

An hourglass sandwiched between two silhouetted faces like :

except not back to the future :P

  the hourglass will have grains of sand (representing time obviously) passing through it with the un-silhouetted eyes of the faces watching the grains, once the bottom is nearly full the hourglass flips and the process repeats.

This is somewhat a commentary on my own feelings on time and death, I feel that in some ways time was created by those afraid of their own demise(much like the way in which we create gods/an afterlife to appease their own fears of dying).

The concept of a death clock , the wanting to know when you will die raises something of a moral dilemma: is it better to live a life ignorant of when the end will come(an arguably happier life) or one where you spend the rest of your life in fear of your upcoming death and spend the rest of your life attempting to prevent the inevitable. (this is of course based of the hypothetical that clocks work accurately)
