"One way of overcoming the computer-time problem is to develop simple models of the driving forces which avoid that trap."

In humans and other land animals, air gets trapped in the alveoli as the lungs are compressed, forcing nitrogen into the bloodstream. The result can be nitrogen narcosis, or the bends, a painful and life-threatening syndrome that afflicts divers who return too quickly from deep dives.
