I flew off my motorcycle once and thought exactly that thought.
I had only had the bike for a few days at that point and I remember thinking in my head, “welp, this sucks. Gonna die now.” Along with, “wow, that small mistake is going to cost me my life.”
Both terrifying thoughts.
I’m still alive though, my left leg is all messed up, like having the left knee of a 80+ yr old at 36.
