Aside from the various old discussions in regards to the pros and cons of Jumping.
Rather thinking of an auto-skill that diminishes damage taken from small falls, heights of say one or two stories off a building. Believe there's sufficient techniques required, as compared with Climbing, for such to not merely rely off of a body stat.
Perhaps also even balancing (not as a separate or even child skill) to provide some slight pause before falling off an edge, or while moving across some narrow area. Not that we really have such atm.
