Because half the time people bluff themselves off saying that they are going to die but they didnt. AWW and it makes them think that they are living a very lucky but risky life that can cost your life anytime.
whatever is the case. people claim they are going to die for not completing anything etc etc etc because the suffering is like having them dead. However just to point out the fact that dying is almost painless, like you will feel any suffering when you die. so suffering is not death, death is like nothing.
instead when you suffer, sometime you just wish that you are dead.
anyway in case you havnt get my point. if you think you are so screwed, dun say you dead. say you wish that you can just drop dead now.
