Flowers from the Deep

"...He opened the sluices so that a sweet water current might carry him out to the deepest
channel; he tied heavy stones to his feet and they dragged him down to the water-bed" (The Epic of Gilgamesh)

Who in their right mind would plunge himself to the bottom of the ocean? You gotta love ancient literature and mythology :D

From a medical stand point, I would highly recommend against this.

Feel a bit of regret coming on.
