I've had something like 18 concussions in my life time. 10 years ago I would lose hours of time and wake up in weird places not knowing how I got there. Risks vs rewards man you can sit around and be afraid of living life or you can live it and deal with the risks.
I got a concussion in February and couldn't see out of the top left of my left eye for two weeks. It was droopy but I didn't give up riding and probably never will.
Hell in 02 I ruptured my spleen and was air lifted and I still snowboard.
Figure out what you want in life and don't settle.
WTF BA, You should wear permanent bubble wrap around your noggin...thought I was bad with five...
