The background is that Formula 1 driver Fernando Alonso had a high-speed crash during a recent test session and spent several days in the hospital due to a concussion. He is now recovering at home. Today his team announced that he will not drive in the first race of the season on March 14, due to the risk of serious injury if he were to crash again so soon after this incident. http://www.bbc.com/sport/0/formula1/31713292

Some people are speculating that he must have been more seriously injured than official reports have let on, as if a concussion were something that people always recover from quickly. After reading about your experience, the decision for him to miss the race made total sense to me. And I think it was a good decision -- in many sports, people downplay head injuries (and other injuries in general) so they can keep playing regardless of possible long-term consequences.
