Nick Fury's aging has been slowed greatly by the Infinity Formula, a serum created by Dr. Berthold Sternberg. Fury was first inoculated with the serum in the 1940s. Fury took the serum annually for many years. Due to its cumulative effect, Fury no longer needs additional doses to prolong his life span.
Nick Fury has trained as a paratrooper, ranger, demolitions expert and vehicle specialist. He holds an unlimited-tonnage, all-seas license as a commander of ocean-going vessels. Fury has completed Green and Black Beret Special Forces training, and has been an agent of the OSS (Office of Special Services) and a liaison of the MI-5 (British Secret Intelligence). He is a seasoned unarmed- and armed-combat expert, was a heavyweight boxer in the Army, and holds a black belt in Tae Kwan Do and a brown belt in Jiu Jitsu. Fury has honed his fighting skills sparring with Captain America (Steve Rogers), perhaps the world's finest unarmed-combat expert. In his youth, Fury learned to fly planes and wing walking.
