You, me, and all living things on Earth will - some day - die. But some deaths are more gruesome than others.
Anna Gosline of New Scientist wrote a morbid yet fascinating article about what some of the worst ways to die feel (or technically, should feel) like. Take for instance, decaptiation:
Quick it may be, but consciousness is nevertheless believed to continue after the spinal chord is severed. A study in rats in 1991 found that it takes 2.7 seconds for the brain to consume the oxygen from the blood in the head; the equivalent figure for humans has been calculated at 7 seconds. Some macabre historical reports from post-revolutionary France cited movements of the eyes and mouth for 15 to 30 seconds after the blade struck, although these may have been post-mortem twitches and reflexes.

Well, that wouldn't be difficult to achieve :P.

Nothing could prepare me for my father's death five years ago. He died of liver cancer, and for the last few weeks of his life, his health deteriorated rapidly, until he drifted in and out of consciousness. I could tell he still struggled to focus his clouded mind, to no avail. His legs began to swell, and he was jaundiced too. During his final moments, for reasons unknown to me, he snored loudly before dying. This was the most traumatic moment in my life, because I had had no prior knowledge of dying process. The only consolation was all his family was beside him, no matter whether he realized it or not.
