My Uncle Tom
The sea captain that is, in his young adulthood told everyone that he expected to die at age 33, just like the Christ of Nazareth.
Tom was not otherwise a megalomaniac. He did not take himself with undue seriousness.
In fact he lived into his late eighties. Dementia ultimately took him, he having forgotten years earlier the names of the fjords where he hid his Liberty ship from the untersee boats of the Kriegsmarine.
