Could you go into more detail, if you're comfortable?
I use to be a truck driver , and i was close to the edge of the trailer with a skid , i had to turn it , and next thing i know , i don't know if i was tired , i lost my balance and next thing i know i fell to the ground. I dont really remember the impact , no pain immediately because of endorphin. Just the aftermath.
It was just like a 2 meters fall but i was barely able to walk for 3 days , and was close to damaging a lung according to the doc. Imagine falling from 50 or 100 meters, only from that 2 meters fall , its very painful when endorphin doesn't work anymore.
You can watch that tv show , it was called "i shouldn't be alive" , its on youtube now for free. Some of them experience bigger fall and endorphin save them.
But if you die , you wont feel a thing. Dying on impact , there is no time to suffer , you suffer more before the jump because of the fear of jumping. Because when you let go of that bridge its freedom without pain if high enough and it doesn't take much.
