Certainly we do not need quantum mechanics for macroscopic objects, which are well described by classical physics - this is the reason why quantum mechanics seems so foreign to our everyday existence.
Of this I am certain, that no one has ever died who was not destined to die some time. Now the end of life puts the longest life on a par with the shortest... And of what consequence is it what kind of death puts an end to life, since he who has died once is not forced to go through the same ordeal a second time?
