You can't beat the law of averages: If you're active at all, eventually you're going to get injured. Sam is a firm believer in getting second opinions from additional doctors. "Learn about your injury and procedure as well as the people involved, and at all costs avoid general anesthesia," he says. In fact, Sam strongly believes improper anesthesia results in a host of complications, from extended recovery to even death. You have been warned.
