"Quick to anger, always lashing out at whatever came near. He would punch you as soon as look at you; sooner, in fact."

In default Oblivion, your fists can reach to about five feet. This mod increases that number to somewhere around 12.5 feet, a distance just beyond the range of interacting with an NPC.
Keep in mind that this change also applies to NPCs, they'll be able to punch you from a further distance as well.
