news is not enough, Nas fans can also expect an “Illamatic XX” U.S. tour, set to begin later this month. He is scheduled to perform at the Soulfrito Music Festival on Feb. 22 and will enjoy a sold-out two-night stint at Lincoln Center in March.

On his website, there was also an announcement about the upcoming release of a new documentary about his debut album: “In conjunction with the release, ‘Time Is Illmatic’—a feature-length documentary film that examines the album—will be released in 2014.

“The movie, from first-time filmmakers One9 and Erik Parker, delves into the making of ‘Illmatic,’ the social conditions that created it and the music legacy passed down from Nas’ Mississippi-born father and celebrated jazz musician, Olu Dara.

No topic in sports has gathered more attention and publicity than the diagnosis, management, and long-term effects of cerebral concussion. The relevant history of concussion starts in 1905 when President Theodore Roosevelt drew attention to the football 'death harvest'. Soon after, rules started to change to reduce the amount and severity of head injuries in football. Up until 1980, the primary focus regarding concussions was to diagnose a potentially fatal intracranial hemorrhage. While aware of long-term consequences of concussions, the perception at the time was that virtually all concussions would 'clear' with time and rest. Concussion management guidelines gave way to objective neuropsychological testing in the early 1990s with the development of the ImPACT™ (Immediate Post-Concussion Assessment and Cognitive Testing) neurocognitive test.
