Many of us have had a concussion at some point in our life. Alpine riding can hand out some bad ones. Every season I see the posts of someone who got one or know somebody how got one.
I have had 4 or 5. Like many I think... I feel fine and the doctor is just being overly cautious. I'm no exception, with excuses like, "I'll take it easy today", I'm riding with the kids it'll be ok", "I feel fine", "It isn't a bad one", etc...
Here's a link about the possible effects of not following the Doctor's orders.
