I fell in a river learning how to fly fish a couple of years ago, lost my balance because of the waders and slick rocks. As soon I hit the water my friend said I was "gone".
Warning.... too much information.
Anything cold can throw me into extreme flashbacks, I would have to sit in a tin metal tub of ice water pretty much after every session. My perps also drowned me as part of their torture a number of times. They did it in the ice water, cubes and all.... sometimes just dunking me over and over and other times holding my head under while they were raping me. One of the main guys was medically trained who would bring me back doing CPR and other stuff, he stepped in for a number of other things not letting me stay dead. He was also responsible for the surgical stuff.
To this day I have a really hard time having drinks with ice in it, just about always order water with no ice at restaurants. I have to be careful with anything cold, even the winter is very hard for me, just the cold air has potential to cause bad things.
The statistics? 1 in 4, 1 in 6?
...then there's me the imaginary number
