I had a serious neck injury skiing last winter. I quit the ski team, but is it okay to do other sports?

It depends on which sports you have in mind. Medical research has separated sports into categories based on their level of risk. Collision and contact sports such as football and basketball are generally felt to be riskier than noncontact, high-speed sports such as skiing and gymnastics. Noncontact sports such as running and golf are the least risky. Your doctor can advise you about which sports are safe for you based on your particular injury.
