[It was a test, not just for Bourne but for him, so when the other man returned a blow, he blocked and pressed back with a series of jabs -- not aimed for any vital regions, because that would be pointless and unproductive, but they were close enough to where anyone with enough experience could identify what he was doing. Each hit was deliberately planned, precise in its execution, and even though, he no longer had the abilities that kept him from feeling the effects of his age, he'd made a point of keeping himself in top physical condition.

Varying the force of each blow to keep his warden on his toes, he mixed it up near the end with a few sharp punches and a kick, harder than any of the previous blows. Again, nothing vital being aiming for, but he could have if he wanted.]
