This could be breaking the rules in which case I apologise, because I talk through the first half of this upload.
I have cancer and due to the treatment found that I no longer produce cortisol which is our bodies natural form of adrenalin. I recently canned out of an ocean kayak and besides not having that heart thump designed to save us through the fight or flight response, makes it really interesting when you are upside down in the water.
It's about how I couldn't find the words to explain what happened to me.
