Here's how I WON'T die: like Japanese author/poet/filmmaker Yukio Mishima.
He committed hara-kiri (seppuku) after a comically failed coup d'etat.
He wanted to take over the Japanese government in order to restore Japanese Imperial traditions. So he broke into a military building and kidnapped a commander and tied him to a chair. He then went out on the balcony to make a speech to the soldiers gathered below. His guess of their reaction was WAY off. He expected them to rally but they all just laughed or jeered.
So Mishima went back inside with the intention of committing ritual hara-kiri. He took his best stab at it but was unsuccessful at inflicting the necessary damage to his belly and related innards.
Fortunately he had enlisted someone to chop his head off with a sword in just such an eventuality which, apparently, is not all that uncommon.
Unfortunately, the guy tried multiple times and failed. Finally a second guy took over and successfully beheaded Mishima.
PS - the first failed beheader then set out to commit seppuku - but also failed. But the guy who beheaded Mishima beheaded him.
Anyhoo, I don't expect my death to bear any resemblance to any of that.
