How Do We Eat With Hands Versus With Utensils?

i raises the point that we have various food cultures around the world, and some of them are more inherently based on eating with hands. I don't know if this is generally applicable? If it is, i think it would, you'd have to confine at least this result to foods that could be eaten either way,. Because a lot of foods, you basically can't eat them except with a spoon, i guess, may be slirping from a bowl.
