Are you sure your just not drunk?
All joking aside, that is no good. How did it happen, if you don't me asking?
I was freeriding, hit a patch of ice and went down like a sack of potatoes. I only remember bits and pieces of after the incident, and that included a heck of alot of saying, "I don't remember anything. I don't remember what I did, eat, studied," etc etc. And that was incredibly terrifying. Like whoever it was that said you don't need to lose consciousness completely, it's true!
No concussion here, never had one, but I can tell you what, my helmet saved me from TWO concussions today, two times went over a ridge too fast got airborne and landed backside hitting the back of my head, twice. Not fun. Still a bit sore in the neck, but no blackouts.
THANK YOU HELMET!
Ok, so I can't say I would have had a blackout without a helmet, but I was seeing black spots in my vision after the first one.
