Yeah and you should not. But in supposition he actually did predict his death. How? Well he deliberately slept for 15 extra minutes daily, and assumed (I don't know how did he do it mathematically) that as soon as the 15 minutes per day would add to 24 hours, he would die. And so using this hypothesis, he predicted his death, which actually did turn out to the correct date of his death!.Ho! i never believe in such things
