Since our childhood we have learnt so many things.
Either they are good or bad.
We have also learnt what to do?, what not to do?
If we see that by doing this we will get hurt then we don't do that thing.
We know the consequences because we have felt it before.
Just like we all have got an electric shock at some point of time thats why we keep ourselves careful from electric wires.
So the question is this have we felt the death before?
because even if someone asks you to give very peaceful death you are not gonna accept it also.
May be we have gone through it.
