Ivan, here is my take.
My own definition of death is “ when the bundle of the sets of laws, that are harmoniously operating together, to run our body, when it is turned off, then we are universally dead. Therefore, death is the “possibility of the imposible” has a merit. Where, the possibility of death could be possible any moment, it is therefore imposible to stop it from occuring. Thus, the possibility of the impossible is possible.
