Since so many of the comments here are about chopsticks, I'm curious what folks think the proportion of people in western countries who can use chopsticks is? I assume it follows roughly the introduction of Asian foods into the locales where people live? I learned in my late teens; prior to that, there was really only one Asian restaurant around where I grew up, and it was more of a buffet-style Chinese restaurant where most of the entries were variations on General Tso's chicken or other Americanized menu items. My parents did acquire a taste for Asian cuisine, but never learned to use chopsticks. But we also have relatives of a similar age who literally have never tried Asian food at all, and I'm assuming have also never tried to use a pair of chopsticks.
