737s are work horses, and generally fly a lot. One built in 1994 probably has a lot of hours on it, and I would bet it was sold from some western carrier used to Africa in the first place after it had too many hours to be workable in the developed world. Usually these old planes are put into use as cargo planes instead where the consequences of a crash are less severe.
