"at least such as no man ever survived to tell of -
and the six hours of deadly terror which I then endured have broken
me up body and soul. You suppose me a very old man - but I am not.
It took less than a single day to change these hairs from a jetty
black to white, to weaken my limbs, and to unstring my nerves, so
that I tremble at the least exertion, and am frightened at a shadow.
Do you know I can scarcely look over this little cliff without
getting giddy?" - Edgar Allen Poe, A Descent into the Maelstrom
