The long & short of it is that my brain "riccocheted" around inside my skull and the frontal lobes were severely cut and damaged by some sort of "bony ridges" that are apparently inside your skull, in the front.
It's my understanding that that is where the olfactory bulb is located.
The other lobe/cerebellum damage was simply blunt force trauma to the right side/back of my head due to impacting on blacktop.
I dearly wish my sense of smell would return.
You can't imagine an odorless world....:-\
