MIB, well said.
Here's what I know:
They're a whole lot faster than I am.
They're a whole lot quicker than I am.
They're a whole lot stronger than I am - or probably a half dozen grown men.
They're a whole lot larger than I am.
They can lift multiples of what I can lift.
They can throw really heavy items I couldn't even lift.
They are Masters of hiding.
They have a built-in Ghillie suit.
They can see as well as me in daylight.
They can see much better than me in low light.
They can see perfectly at night.
Their hearing is at least as good as mine.
Their sense of smell is much better than mine.
They can elect to move soundlessly when they choose. I wear boots.
They can climb like nobody's business.
They can approach and do often approach from unanticipated lines of approach that I normally wouldn't consider possible.
They have endurance and power I don't have.
They can throw a lodge pole pine better than I can throw a javelin.
They can throw a softball sized rock with the same velocity I can shoot a ball bearing with a wrist rocket.
They can split a 30-inch tree trunk down the middle with strength alone that I can't.
They are the ultimate woodland predators - and I'm not.
They know every tree, rock, cranny and crevice in their territory - I don't.
They are team predators with tactical excellence - I'm at least aware of that.
Other than that - I hold all the cards.
