One of the beauties of life is death and it is even more interesting with how no one knows when they are going to die. If there was a machine that could tell when someone is going to die, I wouldn't be interested to get it because it doesn't just make sense for me to know when I'm going to die. On a deeper note, I think I might be tempted to go for it when curiosity peaks. But on the other hand, if the machine costs highly, I wouldn't just be bothered. Of what use would it be for me to spend highly on a machine to see when I'm going to die? I could only go for it when I have money in excess.
In this modern age of fast pace of technology, this machine that can detect when someone is going to die is something I think would be in existence one day and when it happens, it's going to cause havoc in the world because it's going to be like a breach into the supernatural world on this natural world and God might decide to end the world on that time.
Back to the question.
Having a machine that can tell when someone will die sounds like a good Idea especially in a situation when someone has been sick and a lot has been spent on treatment. If the family happens to know when the person will die and it appears to be on the line of the sickness, it'll save the family money.
Also, one can use it to cheat heaven and health and that's the case when someone who has been doing evil things, gets to know why they're going to die, they may decide to repent just a few days to the death day and make heaven when they die.
Thanks.
