I had a fall and a "stick" recently off my WR250R doing about 30mph. Knocked the wind outta me, but noting broke. Though for sure I broke something but doc said no - Epic bruising, pain and soreness were my companions for a couple weeks. Last weekend marked 4 weeks since my off, and I had a great ride on that same bike in that same area.
I'm guessing your fall was a just a freak thing, same guy can do the same fall and laugh it off, while the next guy punctures a lung. Same thing can happen walking down the sidewalk, driving your car to work, lifting a box etc.
I love that my GS will take me down gravel roads to get where I want to go, but a steady diet of that is much more delightful on a littler bike.
