When we die, do all the cells die at the same time ? 
If you are shot in the heart, you blood spills outside
or in your chest, your brain is not irriguated any more,
and you die quickly. Your brain cells will die in a few 
minutes, which is the cause of loss of consciousness. But 
your kidney cells will survive for twenty minutes, and 
your nail or hair cells will survive a few hours or days. 
This is linked with the cellular activity, the more 
activity, the more oxygen supply they need.
 
In brief, death is a general concept, and the death of a 
cell does not imply the death of the whole body. Depending 
on theuir activity, the cells are variably different 
regarding resistance to the lack of oxygen.
