Your question is a question that's subjective. Meaning the word things?
As in, if the things are small enough to carry multiples of, do they count as one or are each individually separate items?
If you counts these things as individual things, then one person would essentially only carry 3 things, as per your statement.
Example: I plan on taking a gun(is the ammo another thing?) I could in theory, fill my pockets with ammunition, plus have the gun already loaded. I could also want to take bubble gum to chew, so I only get one piece?
However, if I had to choose exactly 3 things - I would choose to take a hunting knife, 200' rope and one quick fire rifle(w ammo. to boot)
But, it's only in theory.
