Extraordinary news. Scientists in Denmark have designed some kind of technological tool that can apparently predict how long you’ve got left to live. Tests have suggested that its predictions are 78 per cent accurate, which, when you stop to think about it, doesn’t sound all that amazing. But, given the astonishing speed of technological advancement in general these days, scientists are eventually bound to come up with a device that really can predict your date of death with nailed-on accuracy.
