I ask, do we NEED these young men to die horrible deaths at 40, suffocating because their lungs can no longer transfer oxygen to their blood?

Not all of them do, you don't have contact with the others so that's what you see. What percent succumb to your worst case scenario and why them and not others. Was it because they weren't supplied or couldn't be bothered to use safety equipment?
