We can only hope for ourselves and think about safety in advance, doing dangerous hobbies or work. Here is a story from real life about underwater fishing. My friend bought a fishing rod a month ago and went ice fishing alone for the first time. He fell asleep and fell to the side of the hole, and eventually the ice cracked and he went under the ice in all the equipment. He survived only because he tied himself to the shore in advance and managed to get out, though with difficulty, got pneumonia, but survived. He doesn't go fishing like that anymore.
