I don't really cook or eat underdone fowl, not by more than 5 degrees or so anyway.
But things like pork chops and pork tenderloin I cook well below the old-school recommendations. I'll pull at 135 and let it carryover to 140. And it is FAR superior to anything cooked even 5-8 degrees more. And 160? Forget it, there's zero moisture left.
