Hello! a jumper here.
I have said this many times, so I suppose I will summarize it a little, but if you want any details you can ask without hesitation.
15 years, 7 floors, approximately 24 meters.
I jumped without thinking, quickly, one foot on a chair, another on the railing and then I took a breath.
I didn't hit anything, it was a free fall.
I landed on my feet, I broke all the bones in my legs, my hip, 2 crushed lumbar vertebrae and a kidney fell off.
I wasn't unconscious, well maybe for a second, it was like waking up from a nightmare, taking a big breath of air. I didn't feel pain, just a slight tingling, which I don't know if it was my nerves trying to talk to my brain "there's a lot of pain here" or it was my blood coming out.
There was a health center a few meters around the corner, they called doctors and I don't know if they did anything to me, a tourniquet and stuff, I couldn't move anything except my head, if I tried to move my body it was as if with my legs. bent over you try to roll with your body, no pain, just inability to move. Shortly after, I suppose, the ambulance came, they induced a coma and after 15 days of this, several operations and 30 bags of blood donors, the nurses woke me up by slapping me. In the coma I only had nightmares and strange dreams, but so real that the few times I half woke up they seemed real to me. I think that in a coma hearing ambient noise and voices influenced my dreams, they told me that my uncle, my cousin and other relatives who came to see me every day spoke to me and I suppose that then they appeared in the nightmares.
I lost almost my entire right leg, I can't wear a prosthesis, but I can walk with crutches. Titanium nail in the left leg and plate in the ankle, which they were able to remove years later, but they were unable to remove the nail on 3 occasions.
My advice? Don't land on your feet. And if you can't help it, when you do, don't let them find you, you will die from losing all your blood due to your wounds.
