I've been on a motorcycle for over 25 years now and I've had some near misses but nothing serious.
That's an amazing story and lucky you for making it through. I've known of two people in my circle who died from motorcycle accidents and a few more in my community and region who died .... it's also amazing to realize that you don't need to be riding fast in order to get killed on a motorcycle. One woman in my town was at an intersection, moved across in an awkward way, got hit by a truck and neither were moving fast, she just got hit in a particular way, knocked down, pinned down by the truck, crushed and then died on the way to the hospital.
My near death experience was not as dramatic as yours. I was a dumb teen on a four wheeler on gravel. I did a major jump without knowing it out expecting it, launched about 20 feet in the air, landed front wheels first, launched forward and smashed my face in the gravel. Thankfully the atv went flying in a different direction and didn't land on me. I also didn't have a helmet on. I didn't get knocked out and I was aware the whole time. I was just lucky I was fit strong and landed in a lucky way that didn't hurt me too much.
I have a cousin who fell off an atv as a passenger, landed the wrong way, hit her head (again no helmet) severely injured, treated in hospital for a day before she died from injuries.
Motorcycles and ATV are dangerous machines
