Stuck it's a good question of how we cope with the prospect of death after being led to believe the highly improbable tale that we are not going to die. This religious con-trick has enormous traction because at some time early in life we all awake to the horror of being conscious that we die. (Like the Catholic Church knows; a good moment in life to get religion!)
The Victorians coped with death by exposing even young children to the constant funeral rituals of their community, today we distance ourselves from death or make a joke of it at Halloween.
For JWs it is like we were given a cheque for ten million pounds but now we find that it was issued by the bank of toy town. The prospect of everlasting life was an illusion in the first place in fact I heard on the radio this very morning that scientists have drawn the same and rather obvious conclusion from a biological perspective that there is little prospect of a scientific revolution to create immortality.
I think the point is not to go hunting for an immortality substitute but to quickly come to terms with recognising that there never was a prospect of cheating death in the first place.
To have awoken from this conceit puts us in the category of those who have intellectually grown up and recognised the value of making the most our short lives-- because this is all anyone can do.
