This video by musician and entrepreneur Derek Sivers provides several examples of American cultural norms that are counterintuitive in other societies. For example, Americans navigate roads with street addresses, but Japanese streets don't have names. So how do travelers in Japan find a particular place?

much more similiar to the japanese style.
AS for cutlery I side with caveman. Chopsticks are delicate and require practice. They are so designed to enable a person to delicately select a single serving of food and gently place it in ones mouth. A fork/spoon allows anyone (on their first try) to shovel large amounts of virtually anything into the mouth. You don't even have to pay attention to what your eating. Heck with practice you can skip the chewing part altogether... much more efficient.
I miss it.
They do just fine from what I've seen.
You don't automatically know street name do you? You only learn the ones you need to get to. Streets are the same, you only learn the ones you need to take. Same with comparing a phonetic language to a pictographic one... you simply cannot compare the two.
Impractical cultery? Are you referring to chopsticks? It took a while for me to learn to how use them effectively as a kid, but I did, and still use them today when I have Asian food at lunch.
If you can't adapt to thinking differently, you're probably better off not trying.
